This was fixed in r455 (Apr 1st)... I'm not sure if it made the 0.1.9 
release or not (it happened at about the same time), but it's been on 
the trunk for weeks.

I do something equivalent to this (where both python installations have 
a pth file pointing to the src directory of py2app svn trunk, and the 
scripts dir of py2app is in my PATH):

python2.4 `which bdist_mpkg` -z
python2.3 `which bdist_mpkg` -z

... then I move dist/*.zip to the right place, generate md5 checksums, 
edit the data file that generates the html, run a script that makes new 
html and then does rsync over ssh to the server.  Generally I'll do my 
own installation by downloading from the web site and installing that 
to make sure it works (but I only really test python 2.4 packages these 
days).
