Sounds like we have a case of a file that gets included in the tarballs,
but where the makefile rules think it is out of date and tries to
regenerate it.  Either it should always be generated (and not part of
the tarball), or we need to audit the dependencies to make sure that it
does not need rebuilding when used from a pristine tarball.  I'll try to
take a look into this one later this week (my past experience with dist
bugs like this is that they take a good chunk of dedicated time on my
part to get to a real root cause).

So that means that our conversion to using a stamp file is the real
culprit.  It may be as simple as just making sure the stamp file is also
part of the tarball.

Yes, this is correct.
