It is fixable, I was just making sure that you and I were seeing the
same problem -- "that's not a bug, it's a misfeature". Another thing I
discovered this morning is that if MANIFEST is empty, then you *do* get
an exception -- definitely a bug. So at least a "! empty" check of the
file list is required before trying to copy files and create the
tarball; might as well throw in a "isfile or warn" check on everything
at the same time.

Well, it'll print a warning that "foo is not a regular file (skipped)".
Not nice to silently skip things!

Yup, there's another thread about this very issue going on at this very
moment. Everyone who has spoken up (me, AMK, and Harry Gebel) thinks
that it should at least be an option to put the value of sys.executable
in the spec file, instead of hard-coding "python". I think you've
raised another good argument in favour of making this the default, but
I'm biased -- I do think it should be the default. ;-)

The RPM script options are, ummm, not well-thought-out. Possibly
unfinished, I'm not sure. Those are the options I was thinking of when
I said it might have been unwise to attempt to mirror *all* of RPM's
spec file in Distutils options. My inclination is to delete them,
rather than expose a broken interface.

??? I'm confused again.
Try running "bdist_rpm" with the --source-only option, and then see if
you can build from the source RPM directly. About the only way to debug
these sort of problems is to break the thing down, and a *heck* of a lot
of stuff happens between you typing "setup.py bdist_rpm" and the
finished RPM files being moved into dist/. (Just listen to your hard

OK, based on that and Andrew's feedback, I'd say we blame RPM 3.0.3.
Bottom line: building RPMs with the Distutils requires RPM 3.0.4 or
