I can't be sure without knowing how it was built, but probably. The 
python.org python was built for 10.3.9 and above, and one of the points 
of distutils is to pass all the same flags along, so, unless it depends 
on other libraries built only for 10.5, it should be compatible.

$otool -L multiarray.so

multiarray.so:
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, 
current version 88.3.9)

I'm pretty sure libSystem.B is shipped with 10.3.9 (or maybe earlier...)

I think a coincidence is unlikely.

I guess a dmg wouldn't be anything else, so yes.

great, thanks!
