OK, I now have those versions as well, via easy_install [module]==dev  
on each one.  I had tried building them all from svn the other day,  
but failed, perhaps because of having the wrong version of setuptools.

yes, have that

PyRuntimeLocaions contains the value:  @executable_path/../Frameworks/ 
Python.framework/Versions/2.4/Python

Yes.  It also contains a config directory which contains Makefile,  
Setup, Setup.config, Setup.local.

That looks right, I see an empty list as the value of  
PyResourcePackages.

I'm sure.  I've been checking the site-packages directory before and  
after running easy_install, and I've gone through and removed  
old .egg directories (and checked the easy_install.pth) so I can be  
sure I'm getting the right versions.  I've checked to make sure I  
have the current version of the SillyBalls code too.  SillyBalls  
doesn't even use setuptools, so whatever is broken is broken across  
both distutils and setuptools (I haven't dug underneath yet to see  
how these work, so it's still magic under the covers to me).

So still no idea why it's working for you, but not for me.  Anything  
else you can think of?  I followed the instructions in the py2app  
docs for removing old versions of py2app.  If everything is  
encapsulated in the .egg, perhaps I can revert to the earlier version  
that worked?

It was odd: even though I was pretty much being eaten alive, I didn't  
really mind. I suppose it's the same sort of feeling Jesus had while  
on the cross, or how Buddha felt when Mechabuddha beat him up in  
downtown Tokyo. --AJ Packman
