[pymvpa] Trouble running pyMVPA on Mac OS 10.6.6

[Thad Polk]

I'd like to try out pyMVPA on my Mac but am having trouble getting 
started. Following the directions at 
http://www.pymvpa.org/installation.html#install-macos
I first installed the XCode developer tools, added opt/local/bin and 
/opt/local/sbin to my PATH and then issued the command

$ sudo port install py26-pymvpa +scipy +nibabel +hcluster +libsvm
   +matplotlib +pywavelet

which seemed to run through everything although I didn't watch every line 
of output so it's possible something didn't work (BTW: the 
documentation mentions py25-pymvpa but that version was not found).

The subsequent commands from the installation instructions yield the 
following output:

$ port variants py26-pymvpa
py26-pymvpa has the variants:
    gcc43: build with gcc 4.3
      * conflicts with gcc44
[+]gcc44: build with gcc 4.4
      * conflicts with gcc43
    gcc45: build with gcc 4.5
      * conflicts with gcc43 gcc44
    no_shogun: Do not build shogun
    universal: Build for multiple architectures

$ sudo port install python_select
--->  Cleaning python_select

$ sudo python_select python26
sudo: python_select: command not found


Despite this last error, I can start up python and run it (but I 
already had Python installed, so this does not prove that the pyMPVA 
installation worked):

$ python
Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>


However, when I then try to import mvpa2 (or mvpa2.tutorial_suite, or 
mvpa), python can't find the modules:

>>> import mvpa2
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named mvpa2

>>> from mvpa2.tutorial_suite import *
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named mvpa2.tutorial_suite

>>> import mpva
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ImportError: No module named mpva
>>>


I went digging around on my machine and found the following tarball:
py26-pymvpa-0.4_0+gcc44.darwin_10.x86_64.tbz2 in 
/opt/local/var/macports/software/py26-pymvpa. I also found a number of 
mvpa-related python files in /opt/local/share/doc/mvpa/examples.

Thoughts?

Thanks,

Thad
