[Pyobjc-dev] import objc -> Symbol not found: _PyType_Modified

[anurag u. <anu...@ya...>]

My system is Mac OS X 10.5.8 and I have installed python from 
http://www.python.org/ftp/python/2.5.4/python-2.5.4-macosx.dmg because I do not 
want to use System python (python which already comes installed with Mac OS X) 
and have totally removed system python.

Now when I try to install pyobjc it installs, but on import gives error
