The message means almost certainly means that the Python you are using is a 64-bit/32-bit universal version. When you launch Python with -arch i386, you force the Python to run in 32-bit mode so it is compatible with the 32-bit-only version of matplotlib you've installed in it. When you launch Python by default, it is runnning in 64-bit mode so the 32-bit-only C extension modules in that version of matplotlib cannot be loaded. You might want to ask the matplotlib developers to make a 64-bit version available. In the mean time, you could try to configure Eclipse to invoke the python with `python2.7-32`, which is included with distributions like the python.org one to force Python to run in 32-bit mode on OS X. -- Ned Deily, n...@acm.org -- http://mail.python.org/mailman/listinfo/python-list
