I use neither Leopard nor macports, so it may be an issue there, but 
with the python.org python25 and numpy1.3, I have no problems.

note that this is a libgcc error -- you wouldn't need libgcc if you used 
the python.org build...

I don't think this has anything to do with the stripping (or numpy). 
py2app, by default, puts all the modules you need into a zipped archive, 
so any import you do is going to be a problem if zlib is not available.

I suspect this may be a macports/py2app incompatibility -- with the 
python.org python, it probably uses a system zlib, so it hasn't bundled 
up zlib from macports for you.

I'd try asking on the pythonmac list.
