I am having difficulty installing QGIS on my Mac OS X 10.7.5 (Lion). I understand that QGIS requires GDAL Complete 1.10 framework package and Matplotlib Python module. I installed GDAL (which includes PROJ, UnixImageIO, GEOS and SQLite3) and then I installed NumPy. When I try to install QGIS, a message pops up saying that "QGIS requires the Matplotlib python module". I thought I took care of that by installing NumPy.
Does anyone have any advice to share?
