I can't say too much about most of the warnings, though I believe that the
PLplot bindings have a few warnings that could serve to be cleaned up even
when everything goes smoothly. However, I can take a stab at one of these.

Looking at the error message as well as the command, it looks like somehow
the library is being linked without linking in the Perl symbols. This is
good in so far as it is not a PLplot problem, but bad in so far as I have no
idea what do to with it. All of this should be handled by MakeMaker behind
the scenes so... Have you tried updating MakeMaker?

Feels like a weak suggestion, but that's all I've got. :(
