The way I read this question, the PERL5LIB environment variable should be the way to go, and perhaps be the very first thing to try. Just append the user-specific local library folder to the existing value, if it's already set.
All is well. It finds the scipts in the second folder whilst the paths to full installation stays at "urs/bin/perl", so it must have auto undated the path to folder when CPAN installed
