[Pythonmac-SIG] Re: [Pyobjc-dev] [ANN] py2app 0.1.6

[Bob Ippolito]

I did some reorganization of the packages (I put them in a .pth'ed 
directory).  It does clean out some of the old py2app, but fails to 
clean out macholib and altgraph.

If you do this, then it should work, because the "py2app" directory was 
indeed cleaned when you upgraded:
rm -rf /Library/Python/2.3/macholib
rm -rf /Library/Python/2.3/altgraph

Typically bdist_mpkg installers *do* clean their target first, but in 
this case, it's installing to a different location entirely 
(py2app/macholib, py2app/altgraph, etc..), so the old targets were not 
removed.  I didn't bother to test the upgrade scenario when cutting the 
release, so I didn't think to add these additional steps in the 
preflight script.

Future upgrades won't have this problem, as I don't see a need to move 
things around like this again anytime soon :)
