[Qgis-developer] Force QGIS to use a different version of Python in Snow Leopard

[William Kyngesburye]

You can't.  QGIS includes its own python interpreter and links directly to the Python framework.  This ties it to a specific version and distribution (ie system Python 2.6).  You either need to compile your own QGIS to use the other python, or install scipy for the system python.

I'm working on updating my Scipy distribution if you can wait, I just got distracted by the fortran requirement.
