Hi Kevin,

I've run into problems similar to this from time to time while creating
and maintaining ports.  Would you mind posting a link to or the contents
of your Makefile so I can have a look at it?

It's also useful to use "make -V <variable name>" to examine the values
of any variable you're trying to debug, like PYDISTUTILS_PKGVERSION.  I
believe you can even use the colon modifiers (:S, :C, etc.) right on the
command line so you can try different regexps easily.

Regards,
Greg
