Ah.

Here's the rub - /System/Library/Perl appears before /Library/Perl in 
Perl's module search path. So, if different versions of the same 
module appear in both places, the copy in /System/Library/Perl will 
always "trump" the other.

The answer, as with the answer to finding where CPAN puts things, is 
to pay attention to what CPAN is telling you. When you install a CPAN 
module that's an upgrade to a core module, it warns you about this 
issue, and explains how to avoid the problem you're having - use the 
"UNINST=1" option when you run Makefile.PL. This will delete the old 
version in /System/Library/Perl, as well as installing the new one in 
/Library/Perl.
You rock!

Thanks...

I think the UNINST=1 option is only valid when doing a 'make install', 
not when doing a 'perl Makefile.PL'.  I haven't checked this, because 
it's undocumented (anywhere!), and I really hate poking around in 
EU::MakeMaker and EU::Install more than I have to (which is an awful 
lot).

In any case, you can configure CPAN.pm so that it always supplies 
UNINST=1 when doing 'make install', and that should solve your problem.

As for *why* the core lib always seems to appear before the site lib in 
@INC, I admit to being baffled.  Apparently that's the way it is on 
most platforms, and I haven't heard any good reason for it (or actually 
even any bad reason other than "that's just the way it is").

It's probably installing to a location that's not in @INC.  Compare 
the place it tells you it's installing things to what you see when 
you do a 'perl -V' in the shell.
