It sound like you might be using old codebase. I have this commit on
top:

     commit 710428b6387940727a4a7ad72e28238a71a3840a
     Author: Aaron Boman <aaron_at_[hidden]>

         Fix unintentional masking of ImportErrors. Closes #121

And example/hello builds for me.

Even with the current codebase, you might encounter errors if your
user-config.jam or project-config.jam use modules that are not yet
ported, you can solve that by removing project-config.jam,
and pointing to an empty user-config.jam, like so:

    b2 --python --user-config=/path-to-empty/user-config.jam

HTH,
