Here is what I think I will do. Tell me if you think this is an evil use of the command line. I made a little module named "oduleCheck", using BrowserUks idea, that looks like this:

package oduleCheck;
CHECK {
  print "Modules required at compile time for $0:\n";
  print "  $_\n" for values %INC;
}
1;

By calling it "oduleCheck" I can run it from the command line like this if I want to actually run the script:

perl -ModuleCheck test.pl

Or, if I want to just check the modules or I am checking a module I can run it from the command line like this:

perl -ModuleCheck -c File/Spec.pm
