Unfortunately, in removing the dirname/basename stuff I built in the
assumption that the pkgfile paths will never include symlinks or
anything else that needs to be resolved. I'm not sure why they would,
but it's something we support at the moment.  If everybody's ok with
adding that assumption, then the answer is really soon.  If not, we
should go ahead with your patch.  I do have a couple suggestions for
improving it though, which I'll send along separately.
