Not Playing FLAC

Can you give me the result of this command, plz:
listen --mimetype-support

I have the same problem with Listen v.0.6.2.

listen --mimetype-support output:
---------------------------
/var/lib/python-support/python2.6/musicbrainz2/model.py:21: DeprecationWarning: the sets module is deprecated
  from sets import Set
No musicbrainz support (tunepimp missing or version < 0.5)
---------------------------

When compiling, I had "python-musicbrainz2", "libmusicbrainz3-6" + "libmusicbrainz3-dev" installed. There's no libmusicbrainz2 in my repositories.

i installed "python-tunepimp", still no FLAC playback, but I get this output now:
-------------

Can you give the output of "listen --debug 9" while try to play a FLAC file, plz.

Thank in advance.
