Have you installed a copy of Perl then? The stock copy should be 5.8.1.
What do you get if you do a `which perl`?
If the answer is anything other than /usr/bin/perl, then you have
multiple copies of Perl installed, and the commands you're trying should
work if you explicitly use /usr/bin/perl (&/or get rid of the copy of
version 5.8.0 you have if you don't want it).
If the answer is /usr/bin/perl, you stock Perl has been overwritten. You
can either install a fresh copy of Perl into the same place, or you can
try reinstalling OSX (or manually copy the version of /usr/bin/perl off
your installation CDs, but that could get messy fast).

If you have multiple versions -- and want multiple versions -- then you
can explicitly chooose one or the other by invoking them with a full
pathname rather than just the command name:
/usr/bin/perl
/usr/local/bin/perl
/opt/bin/perl
/usr/local/perl/5.8.3/bin/perl
etc.

It should go by the @INC array, yes.
This could again come down to multiple copies of Perl installed.
