py32-matplotlib @1.2.1: py32-six install fails if first installed py32-matplotlib

[mndavidoff (Monte Davidoff)]

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

$ sudo port -vs install py32-matplotlib
$ sudo port -vs install py32-six

Please deactivate this port first, or use 'port -f activate py32-six' to force the activation.

Error: Processing of port py32-six failed

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.

py-six: updated at r109045

[stromnov (Andrey Stromnov)]

Matplotlib is no longer installs its own six package.

py-matplotlib 1.3.0 now depends on py-six in all subports (r109052)
