dnl How do I get configure to find these values for me?
dnl use AC_PATH_PROG to find a likely location, then search likely 
dnl directory paths for the files that you need.  Allow an environment
dnl variable to provide the values, so that if they are in a strange
dnl place, the user can set the environment variable and configure will
dnl use that value (it should still check that the value is valid, i.e.,
dnl the necessary files are in the specified directory)
