Dear List
I'm new to FE methods and I hope to learn about FE methods through 
FEniCS. I posted this question on the FEniCS answers page, but I guess 
that was the wrong place since I have not received any feedback. I hope 
I'll get some help here, because I'm rather unsure about what the 
problem could be.
I installed the FEniCS binary on my MacBook Pro running under MacOS X 
10.6.3 as described in the installation instructions.
Installation seems successful, at least i can open the fenics terminal.
So I 'cd' into

$ 
/Applications/FEniCS.app/Contents/Resources/share/dolfin/demo/pde/poisson/python

and hit

$ python demo_poisson.py

This is what I get:

Traceback (most recent call last):
  File "demo_poisson.py", line 37, in <module>

ImportError:

2): no suitable image found. Did find:
 /Applications/FEniCS.app/Contents/Resources/lib/python2.6/site-packages/dolfin/_cpp.so: mach-o, but wrong architecture

Any help would be very appreciated. I though before I start screwing up 
a clean installation, I just ask for help because it might be a minor 
thing to fix.
Kind regards and thank you for the great work.
