Thanks for your fast help, I think I got an idea now:
Some of the libraries got installed into 
 /usr/lib/python2.1/site-packages
                        ^^
which is the woody default python version. 
(That solves a few of my other problems :-) )

Is there anything special I have to do when installing 
some of the required graphics libraries on woody?

from visual import * 
works, but running a program I get: 

Visual-2002-07-22
Xlib:  extension "GLX" missing on display ":0.0".

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkWidget'
OpenGL initialization failed.
  Unable to create OpenGL display widget
Xlib: unexpected async reply (sequence 0x2b)!

Also ./configure ... gives 
[snip]
include  
checking GTHREAD_LIBS...  -lgthread -lpthread -lglib  
checking GL... no
checking GL with threads... no
checking Mesa... no
checking Mesa with pthreads... no
configure: error: gtkglarea is required on Unix-like systems

Seems that indeed some graphics library is missing or 
in the wrong directory. 
But 
gtkglarea5-dev      1.2.3-1
python-gtkglarea   0.6.9-3
gtkglarea5             1.2.3-1
are installed. 

Maybe my OpenGl support is broken?
xlibmesa-dev
xlibmesa3
are installed, and I'm a bit fixed here, since 
the NVidia kernel drivers require these special 
packages. 

Thanks for your help, 
Nikolai
