This is telling you that the executable contains versions for ppc and
i386 (no x86_64, so no 64bit version). Another way to confirm this is
at the python prompt with: import sys; sys.maxint

Your best bet is adding the breakpoint and stepping through with pdb
until you hit the error (you can usually just hold down the return key
after the first step...)
