.IP "\(bu" 4
Updated for perl\-5.8.8 and perl\-5.9.3 by Ken Hirsch.
.Sp
Simplified the build process by using the \s-1MPEAUTOCONF\s0
functionality in Mark Klein's ld.
.Sp
If you build this from scratch, make sure you have a version
of ld which supports it.  In the shell, type
.Sp
.Vb 2
\&  ld \-\-help
\&    and look for AUTOCONF or MPEAUTOCONF near the bottom
\&
\&  or do this:
\&  ld \-\-help 2>&1 | grep AUTOCONF
.Ve
.Sp
If you see don't see \s-1AUTOCONF\s0 or \s-1MPEAUTOCONF\s0, make sure you get a new
version.
.Sp
You also do not have to use mpeix/relink after building, so the
recommend sequence is:
.Sp
.Vb 1
\&  ./Configure \-de
\&
\&      # or ./Configure \-de \-Dusedevel 
\&      # if you\*(Aqre building a development version
\&
\&  make
\&  make test
\&     # if you run this in a job, do "make test_notty"
\&
\&  make install
.Ve
.Sp
Be prepared for a wait. These take much longer on MPE/iX than on a Unix
system, because of a slow forking, mostly.  On a lightly-loaded \s-1HP3000\s0
Series 979 running MPE/iX 7.5:
.Sp
.Vb 3
\&    Configure: 1 hour
\&    make:      1 hour 15 minutes
\&    make test  1 hour 45 minutes
.Ve
.Sp
Various socket problems were fixed in mpeix.c.
.Sp
Mark Klein provided a fixed sigsetjmp (that works with dynamic
libraries) in mpeix_setjmp.c

Rebuilt to be compatible with mod_perl.  If you plan on using
mod_perl, you \s-1MUST\s0 download and install this version of Perl/iX!
.IP "\(bu" 4
uselargefiles=\*(L"undef\*(R": not available in \s-1MPE\s0 for \s-1POSIX\s0 files yet.
.IP "\(bu" 4
Now bundled with various add-on packages:
.RS 4
.IP "\(bu" 8
libnet (as seen on \s-1CPAN\s0)
.IP "\(bu" 8
libwww-perl (\s-1LWP\s0) which lets Perl programs behave like web browsers:
.Sp
.Vb 4
\&    1. #!/PERL/PUB/perl
\&    2. use LWP::Simple;
\&    3. $doc = get(\*(Aqhttp://www.bixby.org/mark/perlix.html\*(Aq);  # reads the
\&       web page into variable $doc
.Ve

.IP "\(bu" 8
mod_perl (just the perl portion; the actual \s-1DSO\s0 will be released
soon with Apache/iX 1.3.12 from bixby.org).  This module allows you to
write high performance persistent Perl \s-1CGI\s0 scripts and all sorts of
cool things. (http://perl.apache.org/)
.Sp
and much much more hiding under /PERL/PUB/.cpan/
.IP "\(bu" 8
The \s-1CPAN\s0 module now works for automatic downloading and
installing of add-on packages:
.Sp
.Vb 3
\&    1. export FTP_PASSIVE=1
\&    2. perl \-MCPAN \-e shell
\&    3. Ignore any terminal I/O related complaints!

Perl's \fIgetpwnam()\fR function which had regressed to being
unimplemented on \s-1MPE\s0 is now implemented once again.

This is the official home page for the \s-1HP\s0 e3000 MPE/iX
( http://www.hp.com/go/e3000 ) port of the Perl scripting
language ( http://www.perl.com/ ) which gives you all of the power of C,
awk, sed, and sh in a single language. Check here for the latest news,
implemented functionality, known bugs, to-do list, etc. Status reports
about major milestones will also be posted to the \s-1HP3000\-L\s0 mailing list
( http://www.lsoft.com/scripts/wl.exe?SL1=HP3000\-L&H=RAVEN.UTC.EDU ) and
its associated gatewayed newsgroup comp.sys.hp.mpe.
.PP
I'm doing this port because I can't live without Perl on the Unix
machines that I administer, and I want to have the same power
available to me on \s-1MPE\s0.
.PP
Please send your comments, questions, and bug reports directly to me,
Mark Bixby ( http://www.bixby.org/mark/ ). Or just post them to \s-1HP3000\-L\s0.
.PP
The platform I'm using to do this port is an \s-1HP\s0 3000 957RX running
MPE/iX 6.0 and using the \s-1GNU\s0 gcc C compiler
( http://jazz.external.hp.com/src/gnu/gnuframe.html ).
.PP
The combined porting wisdom from all of my ports can be found in my
MPE/iX Porting Guide (http://www.bixby.org/mark/porting.html).
.PP
\&\s-1IMPORTANT\s0 \s-1NOTICE:\s0 Yes, I do work for the \s-1HP\s0 \s-1CSY\s0 R&D lab, but \s-1ALL\s0 of
the software you download from bixby.org is my personal freeware that
is \s-1NOT\s0 supported by \s-1HP\s0.

MPE/iX 5.5 or later. This version of Perl/iX does \s-1NOT\s0 run on
MPE/iX 5.0 or earlier, nor does it run on \*(L"classic\*(R" \s-1MPE/V\s0 machines.
.IP "\(bu" 4
If you wish to recompile Perl, you must install both \s-1GNUCORE\s0 and
\&\s-1GNUGCC\s0 from jazz (http://jazz.external.hp.com/src/gnu/gnuframe.html).
.IP "\(bu" 4
Perl/iX will be happier on MPE/iX 5.5 if you install the \s-1MPEKX40B\s0
extended \s-1POSIX\s0 filename characters patch, but this is optional.
.IP "\(bu" 4
Patch \s-1LBCJXT6A\s0 is required on MPE/iX 5.5 machines in order to
prevent Perl/iX from dying with an unresolved external reference
to _getenv_libc.
.IP "\(bu" 4
If you will be compiling Perl/iX yourself, you will also need
Syslog/iX ( http://www.bixby.org/mark/syslogix.html ) and the
