 The installation of py-six @1.3.0 fails if py32-matplotlib @1.2.1 is
 already installed.

 It appears that py32-matplotlib installs its own six package.

 {{{
 $ port contents py32-matplotlib | grep six
 /opt/local/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2
 /site-packages/__pycache__/six.cpython-32.pyc
 /opt/local/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2
 /site-packages/six.py
 }}}

 Both packages install without errors if I install py32-six first and then
 py32-matplotlib. The attached patch appears to fix the problem. It changes
 py3*-matplotlib to depend on py3*-six. It also adds a py33-six subport for
 the py33-matplotlib dependency.
