possibly.

randy suggested asking p5p, which might be a good thing to do.  I understand
the position on File::Spec, and I guess that sounds right.  but if there is
no module currently available that will strip out all the platform dependent
goo (symlinks, parent directories, short filenames) so that two paths that
end up at the same file can be compared for equality then I guess it's time
for one.
