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

I'm installing software on a new MacBook. I'm not yet very facile with Macs.

I have python 2.6.5 from python.org installed, but the vpython installer
says that I have to install python 2.6 before it will proceed.  I think the
problem may be that python is not installed in it's default location.
 Python was installed as part of the Enthought Python Distribution, which
installs python and a bunch of other stuff that I use.  The python
executable ended up being

/Library/Frameworks/Python.framework/Versions/Current/bin/python

1.  Is this indeed *not* the default location for a "regular" installation
of python?
2.  If it is not, is that possibly the cause of my problem?
3.  Can I fix it by
   a. creating a symbolic link somewhere (what would it be?)
   b. or telling vpython where to look for python (set an environment
variable?)
4. Or am I wrong, and the problem lies somewhere else?

Thanks,
gary
