Perl CPAN: Changing the compiler
 

Hi. I have this annoying little hitch: I'm trying to use CPAN to install a Perl module I need onto a system on which I have no root privileges. However, the system has two C compilers: gcc annd pgcc. For reasons I do not understand, CPAN attempts to use pgcc instead of gcc, and of course all build attempts fail because pgcc does not recognize most of expected compiler switches. I need to tell CPAN to use gcc instead of pgcc, but I have no idea how to do this. There does not seem to be such and option listed with "o conf".

I know it is possible to set this if I do not use CPAN, and install manually, but this will be a real pain because I must then install the dependencies manually.

Checking perl for compiler configuration :
$ perl -MConfig -e 'print "$Config{cc}\n"'
... The reply will most often be : gcc .

The most easy way of setting a specific compiler for perl, example :
$ mkdir $HOME/bin && cd bin/ && ln -s /usr/bin/gcc
... And then set $HOME first in your PATH :
PATH = $HOME/bin:$PATH

It's not CPAN. See http://perldoc.perl.org/Config.html , look for compiler there.
