Is it really necessary to import GTK when installing MPL? why? I think getting rid of that requirement would be the best fix.
Basically, you need to be able to
make sure you can launch an X11 app (eg xterm) in the environment that
you are running matplotlib install.
Perhaps some UNIX guru can give the proper incantation.
I've done it, but I'm not sure I remember how at the moment. But try something like:
xhost +root
or even:
xhost +
which I think lets anyone have access to the Xserver.

Exactly this was the problem. I was logged in from machine A on machine B as user (ssh -X B) and wanted to install on B. So what I did on B was:
(as user):
user@...1000...:<mpl_path>$ python setup.py build # this works
(via sudo):
user@...1000...:<mpl_path>$ sudo python setup.py install
python setup.py install installing data to
lib/python2.3/site-packages/matplotlib/mpl-data
pygtk present but import failed
Using default library and include directories for Tcl and Tk because a Tk window failed to open. You may need to define DISPLAY for Tk to work so that setup can determine where your libraries are located.
Gtk-WARNING **: cannot open display:
(becoming su):
user@...1000...:<mpl_path>$ su
user@...1000...:<mpl_path># python setup.py install
X11 connection rejected because of wrong authentication.
The application 'setup.py' lost its connection to the display localhost:10.0;
most likely the X server was shut down or you killed/destroyed
the application.

Right, I can't open an X app on B via sudo or beeing su. Unfortunalelly I don't understand enough of the X-permission/xhost stuff to get this right

He did. Finally I logged in as root (ssh -X root@...1000...) and then everthing
went fine.
================================================================================================
Additionally, if you want to install directly on A or B (not beeing logged in via ssh) just open a root terminal and install as usual. sudo and su won't do it.
