pymca has depreciate messages on console startup

I am on Ubuntu12.04 64bit.

A start of pymca from console shows:

user@userhost:~$ pymca
/usr/lib/pymodules/python2.7/sklearn/hmm.py:24: UserWarning: sklearn.hmm is orphaned, undocumented and has known numerical stability issues. If nobody volunteers to write documentation and make it more stable, this module will be removed in version 0.11.
  warnings.warn('sklearn.hmm is orphaned, undocumented and has known numerical'
/usr/lib/pymodules/python2.7/sklearn/cross_val.py:2: UserWarning: sklearn.cross_val namespace is deprecated in version 0.9 and will be removed in version 0.11. Please use sklearn.cross_validation instead.
  warnings.warn('sklearn.cross_val namespace is deprecated in version 0.9'

The message for the hidden markov model is problematic with "has known numerical stability issues".

This should be fixed before it causes bugs.
