This bug also applies at least to Fedora 14 and 15.

Actually the error on Fedora is slightly different, although it is most likely 
the same problem:

I can confirm that the error reported in the original post also appears on 
Ubuntu 11.04.

Just to close this issue:

The easy_install sandbox violation was fixed in r32 on 25 October 2011.

@ubershmekel: The correct way to select the mplh5canvas backend is:

  import matplotlib
  matplotlib.use('module://mplh5canvas.backend_h5canvas')

The module notation is necessary because the backend is not integrated into 
matplotlib itself.
