The Exporter does not report a pathname if the module name contains '​::'.
Here are two examples; the first works fine, the 2nd shows the problem​:

  % perl -MCwd=99 -e0
  Cwd 99 required--this is only version 2.01 (/ora2/jdl/PERL/dest/lib/perl5/5.00503/Cwd.pm) at -e line 0

  % perl -MData​::Dumper=99 -e0
  Data​::Dumper 99 required--this is only version 2.101 at -e line 0
  BEGIN failed--compilation aborted.

What I would expect for the latter​:

  % perl -MData​::Dumper=99 -e0
  Data​::Dumper 99 required--this is only version 2.101 (/ora2/jdl/PERL/dest/lib/perl5/5.00503/Data/Dumper.pm) at -e line 0
  BEGIN failed--compilation aborted.

Here's the patch to fix it. It's been tested against hpux & win32.
