I am running macports to install scipy and such on OS X leopard with python 2.7. The install runs successfully, but running python and trying to import the packages I've installed, they're not found. What I'm running is: sudo python_select python27 sudo port install py27-wxpython py27-numpy py27-matplotlib sudo port install py27-scipy py27-ipython Opening up python in interactive mode (it is the correct version of python), I type 'import scipy' and get a module not found error. What gives? How can I find out where it is installing the packages to instead?
