Problems with perldoc

[Rodolfo Aramayo]

IMPORTANT DISCLAIMER: This issue might not be related at all to
MacPorts as I have installed perl modules (not available via ports)
using CPAN...

I noticed that when I issue the command, I get:

You have an old groff. Update to version 1.20.1 for good Unicode support.
If you don't upgrade, wide characters may come out oddly.

I tried re-installing the "pod" ports without results...

Any Ideas on how to fix this?
Do I need to uninstall everything--ALL perl 5.12, including my
perl5.12 and start over?

Thanks
