#14 ImportError when installing on Mac OS 10.5.8

[Anonymous]

I am having problems installing rpy2-2.2.2 with R 2.15.0 on Mac 10.5.8. I have tried several previous versions of RPy and R but get the same error. I am running Python 2.7.2 via the Enthought distribution and using the spyder interface.

The install via python setup.py build install appears to work fine. However, when I try to test or use rpy, through either
python -m 'rpy2.tests' (from Terminal)
from rpy2.robjects import r (from Python)

I get the following error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/EPD64.framework/Versions/7.2/lib/python2.7/site-packages/rpy2/robjects/init.py", line 14, in <module>
import rpy2.rinterface as rinterface
File "/Library/Frameworks/EPD64.framework/Versions/7.2/lib/python2.7/site-packages/rpy2/rinterface/init.py", line 78, in <module>
from rpy2.rinterface._rinterface import *

Referenced from: /Library/Frameworks/EPD64.framework/Versions/7.2/lib/python2.7/site-packages/rpy2/rinterface/_rinterface.so

Any help would be appreciated.
