Agreed.

Right, that's what I have Bricolage doing:

   require Bric; our $VERSION = Bric->VERSION;

No, I think that that probably is enough. But I don't have a solution  
for this for my JavaScript libraries. In fact, all of my CPAN modules  
have the version number hard coded in every module, too. Whenever I  
have a new version, I execute a script to update it:

increment_version.html

I recently modified the regex to work with JavaScript library  
versions, too.
