The Makefile.PL or the MakeMaker module or whatever it is that's
making the path contain /usr/local/lib rather than using /usr/lib
needs to be fixed. I don't know whether this is in the Perl code
itself or in the module, but it's broken IMO.

Yes, that's OK.

The Perl package(s) need to provide a program to manipulate this .pod
file. Is it in a difficult format ?
