One worry I have is that the versions required by VPython may not
necessarily match well with the versions supplied by the user's Linux
distribution.  As a specific example, the current 'stable' Debian
distribution (code name "Woody") has python-2.1.3 as its standard python.
I'm unclear whether or not a user can safely make '/usr/bin/python' be
python2.2 without possibly affecting other software installed on the
system.  In fact, in my experience with Vpython (which, admittedly, is
only 1 year long) the requirements of VPython (e.g. python version,
gtkglarea, numeric) have *never* been in agreement with the packages
available from my distribution.

Now I'm quite happy to install everything from source, so I always install
all vpython-related things into '/usr/local' or equivalent so as to not
overwrite the system versions.  If an automated Linux installation scheme
is going to update stuff in /usr/bin, then it had better do so with
extreme care.
