FEniCS out-of-box example fail

    Dear Forum
    Is anyone using FEniCS to perform finite-element method calculations? I want to work myself into PDE's and I found this Python based software. After installation, I tried to run the example, but I get the following error:
    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
    Code (Text):

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

    Code (Text):

    $ python demo_poisson.py
    This is what I get:

    Code (Text):

    Traceback (most recent call last):
      File "demo_poisson.py", line 37, in <module>
        from dolfin import *
      File "/Applications/FEniCS.app/Contents/Resources/lib/python2.6/site-packages/dolfin/__init__.py", line 13, in <module>
        from dolfin.cppimports import *

        _cpp = swig_import_helper()

        _mod = imp.load_module('_cpp', fp, pathname, description)
    ImportError: dlopen(/Applications/FEniCS.app/Contents/Resources/lib/python2.6/site-packages/dolfin/_cpp.so, 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. Unfortuantely, no real help from the FEniCS page yet, that's why I'm here.
    Kind regards and thank you for the great work.
