confused and need help

[John Michael]

Hi I wanted to update my apache and mod-perl install. I stated to do it and found that I needed the LWP module which requires some other modules first. I got all of them on untill I needed the libnet module. ALl of the other modules I installed by hand and having no problems until I needed the libnet module. I could only find it in the Bundle::libnet module and that has to be run from the CPAN module.  In an attempt to install Bundle::libnet which you have to do through CPAN it seems that CPAN installed another version of perl on my server in usr/local/lib/perl5/5.6.1 I already have a version in usr/lib/perl5/5.6.0   Did it automatically try to update my version?   When I run perl -MCPAN -e shell it is being run from the 5.6.1 version at usr/local and therefore does not find any of the other modules I already have installed. I know this because it uses the cpan config file in that location and also the dependencies that it is showing are already installed in the other location.   Can I just delete the 5.6.1 version off of my server?   How do I get the 5.6.0 version of cpan to run and the server to recognize this?   Also, I am running a mod-perl server and have many scripts running under it. How does the server know which version to use?   Am I going to have some problems?   I'm not sure what to do at this point and don't know where to look.   I now have to versions of perl on my server.  I assume there is a file somewhere that tells the computer which one to use when you type perl from the command line.  What should I do?   Thanks John Michel
