[Pythonmac-SIG] Problems with universal Python 2.4.3's distutils

[Anand Patil]

Hi all,

I'm running Universal Python 2.4.3 on my Powerbook G4 under OS X 10.4.8. 
I'm trying to install a package called mpi4py (MPI for Python), and 
Universal Python's distutils seem to be causing some trouble. It looks 
like the -arch i386 argument is confusing the linker somehow because my 
computer is a PPC. Also, I'm not sure what the library rt is, but there 
doesn't seem to be such a thing on my computer (though I've installed 
the latest version of Xcode). Does anyone know how I can resolve this? 
Sorry if this is OT, I didn't know where else to post.

Thanks for any advice,
Anand Patil
