This is exactly the reason why I think it was a major mistake of the
perl people to include even more and more modules in the distribution. A
year or so ago, I spend a huge amount of time trying to conditionalise
the dependencies for modules now included in 5.8, only to find out that
this might not be the best solutions after all. Modules should be
modules, not distribution!

I agree with Lars that this is a non-trivial issue. The modules now
included in the distribution, don't stand still and other modules are
going to depend on newer version of those, that are not in the
distribution. Adding and removing the dependency depending on if the
module has a newer version on CPAN than in the distribution might be the
techinically best solution, but it's practically infeasible. I think
that the best way is to keep the dependency, as long as it doesn't
overwrite files from the distribution.
