This may be just a warning message [1]. Did this create any .so files? What happens if you run (in the PyMVPA root directory):

    find mvpa2 -iname '*.so'

On my system (also running Yosemite) I get:

    $ find mvpa2 -iname '*.so'
    mvpa2/clfs/libsmlrc/smlrc.so
    mvpa2/clfs/libsvmc/_svmc.so

If that does not return any matches in your case, what is the output of:

    find . -iname '*.so'

This may be a path issue. Did you add the PyMVPA path to the PYTHONPATH? 
On my system, I use:

    export PYTHONPATH=/Users/nick/git/PyMVPA:${PYTHONPATH}

where "/Users/nick/git/PyMVPA" is the PyMVPA root directory on my system. 

(by adding this line to ~/.bash_profile, this is run every time a new Terminal window is opened.)
