Maybe the simple solution is to make a copy the script and in the copy.

  1. Comment out or delete any "use vars ..." lines.
  2. edit out any "our" keywords.
  3. Syntax check with "perl -wc copy.pl"

That ought to produce output somethng like: 

P:\test>perl -wc junk.pl
Global symbol "$c" requires explicit package name at junk.pl line 8.
Global symbol "$rv" requires explicit package name at junk.pl line 9.
Global symbol "$c" requires explicit package name at junk.pl line 10.
Global symbol "$c" requires explicit package name at junk.pl line 11.
Global symbol "$c" requires explicit package name at junk.pl line 12.
Global symbol "$c" requires explicit package name at junk.pl line 12.
Global symbol "$c" requires explicit package name at junk.pl line 17.
Global symbol "$rv" requires explicit package name at junk.pl line 22.
Global symbol "$c" requires explicit package name at junk.pl line 22.
junk.pl had compilation errors.

Is that the sort of information you are after?

There is also a module Devel::Something (Xref?) that produces a cross reference listing, but cpan appears to n down right now.
