One of problems with CPAN [for our use] is the requirement of a c
compiler. Not all modules, but some do need to be compiled and they need
to be compiled with the same compiler that perl was built with. [Under
Solaris there is a work around called perlgcc -> /usr/perl5/bin/perlgcc
-MCPAN -e shell]. 

But even so not all production boxes are going to have a compiler.
Better to stick with perl solutions that we simply stick in the ~/lib

As far as the issue with system calls mentioned I know I sort of brought
up getting rid of cat and zcat and df and whatever the biggest problem
is speed I think. We will be hard pressed to make a perl routine that is
faster the cat.
