This variable is analogous to $PATH; it lists directories in which
the Python import mechanism will search for modules. The
interpreter supplements this list with some paths it knows itself;
for the complete result, launch the Python interpreter (by typing
'python' at your shell prompt) and type
Unlike $JAVA_HOME, for example, $PYTHONPATH does *not* give the
path to the Python installation.
I don't know what viewcvs is, but a typical application does not
require any modification to $PYTHONPATH unless it is installed in
a weird place. Normally Python modules get installed into, e.g.,
/usr/lib/python2.2/site-packages, which is among the directories
the interpreter uses automatically.

It is populated like any shell variable. It should be blank when
the interpreter's default paths are sufficient.

The obvious places are /etc/profile and ~/.bashrc, as appropriate.
... but none of this seems obviously relevant to your objective.
Is viewcvs not working? If not, what is the problem?
