Jiminy Crickets. I think I'm looking in the right spot, but I'm not positive. I went to perl.org, then mailing list archives, and took a peek at the perl.macosx
archive. Over 8000 messages, no search function.
In my brief look through the messages, I noted a message which suggested that perlfunc.pod and perldiag.pod are missing from the default Perl installation. Is this perhaps what you were thinking of?
I do have the Developer Tools installed, so I'm not sure if my copies of the above pod files were installed when I installed the Developer Tools or the System. But they're certainly both on my system.
