mapnik: fix compile error with system Python
Mapnik by default tries to install to the site-packages in /System
when brewed against system Python. This causes a build error
because that directory is not writeable. Mapnik correctly
determines the versioned site-packages name without modification,
but for Homebrew it needs the proper prefix.
* Add the standard `which_python` function to the formula.
* Add a scons argument for `PYTHON_PREFIX`
* Add the standard caveat for `PYTHONPATH`.
Discussed upstream: https://github.com/mapnik/mapnik/issues/1155
and tested on Lion against the system Python.
Fixes #11389
Closes #11407.
