Thanks Achim! I think what happened was that somewhere along the line I 
installed something with cpan that wanted to upgrade that module, and I 
had setup to add my cpan updates to a personal directory which I put at 
the front of my Perl5 lib path... When the core got updated, the newer 
version was hidden behind the personal directory. It's always something! 
Reinstalling was next on my list.
