A problem opposite to the one that you mentioned also occurs:
building on different machines with different packages that solve the
same virtual dependency (e.g. Xorg vs. Apple's X11) will generally
result in more than one MD5 for the same package.
Hmm... Then, wouldn't that be a problem for bindist in general?
It is clear that systems which want to contribute to the bindist must
satisfy a certain number of health safety standards, for example
- Fink must be installed in /sw which is not a symlink to some other
place (because the true Fink root will be hardcoded in a few packages)
- X11 must be Apple's X11, not some other flavor
- perl must be Apple's perl
- the dev tools must be the latest released Xcode, no prerelease stuff
- fink itself must be a released version, no CVS HEAD or other branch
There are certainly quite a few other similar rules of hygiene to
respect that will all but exlude package building for the bindist on
your run-of-the-mill Fink developer system.
Even respecting all those standards will get you different MD5s on
different systems. This is indeed already a well-known problem now: If
you run "fink -b install" or "apt-get dist-upgrade", it will happily
download and install a bunch of binary packages for versions you already
have installed. And apt-get doesn't even compute MD5s. See the thread
http://thread.gmane.org/gmane.os.macosx.fink.devel/11027 for more details.
Having said this, I would be very happy if we found a system that
allowed us to populate the "current" subtree of the bindist in between
releases. There are quite a few broken packages in the bindist (maxima
and pari-gp, to name two of them that embarrassed me yesterday(*)), but
they are not vital, so nobody bothers to put a corrected version into
the bindist.
(*) The author of TeXmacs tried to see how his program works on the Mac,
so he downloaded the 0.8.0 installer and followed instructions. Then he
described his experience to me. In short, it was a catastrophe; two of
the more blatant bugs being that the maxima and pari-gp plugins were not
working. They are working with more recent versions, of course, but not
with the stuff from the bindist.
