SUSE 9.0 - Uh, oh.  (see below)

That doesn't work for the Visual-2004-07-22.zip package, and is the
source of the ImportError below.  Part of VPython is written in C++, and
part of it in Python.  The two must come from the same release of
VPython, ie, you must perform a full install.

You have version mismatch between the old cvisualmodule.so and the new
visual/*.py files.

Suse 9.0 is known to have shipped with a broken compiler.  You must
install GCC and Boost from source to correct the problems with your
broken compiler. 
http://www.vpython.org/Building%20VPython%20on%20SuSE.html

Also, since SUSE installs GNOME into /opt/gnome, you will need to set
the CPPFLAGS environment variable to include "-I/opt/gnome/include" when
running Visual's configure script.
