In your environment.
Where that lives deopends on your OS and how you see it depends 
on your shell.

Looks like a *nix OS so try typing env to see the environment vars.

To set the variable you need to edit your .profile file or 
your .login file depending on the shell...

In csh and derivatives its

$ setenv PYTHONPATH  .:/home/xyz/pov/povray-3.5

In Bourne shell derivatives you need something like

$ export PYTHONPATH=.:/home/xyz/pov/povray-3.5

That means it's not set yet.
