[gentoo-user] Crufted with perl modules?

[Grant]

I was having trouble getting g-cpan to work with a Bundle of CPAN perl
modules and I got frustrated and started to install it with perl
-MCPAN -e instead.  After a little while I thought better of it and
exited the installation, but should I now have perl modules spread
across my filesystem that aren't known by portage?  Is there any way
to clean them up?  Would installing the same Bundle with g-cpan be
guaranteed to straighten everything out?
