Hi John,
I made those changes. But it seems like the following keeps launching Ember's python instead of YT's python-2.6.3.
[sagarwal at ember ~]$ which python
/usr/bin/python
[sagarwal at ember ~]$ python
Python 2.6 (r26:66714, May 5 2010, 14:02:39)
[GCC 4.3.4 [gcc-4_3-branch revision 152973]] on linux2
Type "help", "copyright", "credits" or "license" for more information.

These problems are related. Problem 2 is happening because you're
trying to append $PYTHONPATH to itself when it doesn't exist in the
first place, as the error message says. Remove the ":$PYTHONPATH" from
the setenv command, and it should work. Then source your .cshrc file,
and you should be able to import yt in python.
