Administering Perl

[tree]

I have a question on administering perl..

I recently upgraded perl on the box from 5.6 to 5.6.1 and now i'm seeing
alot of these "Subroutine redefined" messages.  what is a "subroutine
redefined" message??

I also had to reinstall alot of CPAN modules.. i'm probably being
boneheaded and there's documenation about this somewhere.. but how can I
avoid re-installing all the cpan modules i've installed when i upgrade
perl?  is it as simple as copying them over?
