dnl Check if installed version string is equal or higher then required. 
dnl This is used in a couple of tests to ensude we have a valid version 
dnl of a software package installed. The basic idea is to split the 
dnl version sequences into three parts and then test against eachother
dnl in a whole complex if statement.
