I think that's the problem to fix: compile-first isn't supposed to run
in this case, because all the *.elc files are already present in the
tarball.  Can you figure out why does compile-first run? which one of
the *.elc files it depends on is outdated?

This (also) regenerates *.elc files that are supposed to be in the
tarball, which is not what we want.

Thanks.
