installing PyRosetta on non-Intel-based Mac platform

from tech support email:

I just started experimenting with PyRosetta on a G5 PPC machine running Mac OS X 10.5.8. However, I'm getting the following:

OSX> ipython.py
Leopard libedit detected.
Python 2.5.1 (r251:54863, Jun 17 2009, 20:37:34)
Type "copyright", "credits" or "license" for more information.

IPython 0.9.1 -- An enhanced Interactive Python.
? -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.

...does this mean I need an Intel-based machine to run the package?
