Re: [Visualpython-users] Problem installing on Mac (non-default python location perhaps?)

Bruce,
	It is actually a little worse.  When I dealt with this two years ago, an additional problem was that the numpy that came with enthought was different from the one in the visual package.  So, after installing visual, the extra packages in the Enthought distribution like scipy would crash;  if I went back to enthought's numpy, then visual would crash.  I finally found it easier to install the enthought distribution and then build visual using the enthought numpy.

Gary, as a test you might install VPython on the standard Python 2.6 (maybe on a different Mac) and save a copy of the files that go into site-packages, then on your Enthought machine just copy those files into site-packages. If the Enthought Python is in fact an instance of Python 2.6, this should work.
