Re: Arghh! Makefile mysteries...

Maybe so.  Anytime setuptools is involved, I suspect just that.  That
bug is still in the setuptools tracker.

But I created a Makefile with just this in it:

all:
        python -c "import os; print os.environ.get('PYTHONPATH')"
        python -c "import sys; print sys.path"
        python -m jcc --version

And then I do a "make all" on it.  The last line errs out, but does so
with the right stack trace, if PYTHONPATH is set.  What I don't understand
is what the difference is between this and the PyLucene Makefile.

No thanks.  Just more complexity to manage.  I'd like to get setuptools
out of the mix.  It's easy_install.pth that's screwing up the sys.path
order.
