This looks correct.  But is there another *.pdmp file somewhere on
your system, like in /usr/local/bin/, where the Emacs executable file
is installed?

I don't think I follow: what do you mean by "evaluating the relative
pathing"?

Alos, are any of the files/directories involved in this hard or
symbolic links? if so, can you show where each link points, i.e. the
real target files/directories of each link?

If the above doesn't give any clues, maybe we should find such a
commit.  But I would prefer first to understand better what happens
with the current master branch.
