If you are starting with PyMVPA today, trying 0.6.dev is the right thing
to do. However, updating the documentation to match this code is what we
are working on right now. Fortunately, we already finished updating the
tutorial that you can find at

This happens because the module doesn't exist in 0.6 anymore. The
comparable 0.6 import would be

  from mvpa.datasets.mri.fmri_dataset

please take a look at the tutorial for more details.

If your are having difficulties, please report them. Since 0.6 is quite
fresh there are probably some rough edges and we'd be glad to iron them
