The sparse matrix normal package is an add-on package that must be 
installed explicitly. It seems that the Python part of the package is 
in the standard distribution and the C part is not available at all 
since the current Web site was installed.

Since I haven't used this module for a long time, I haven't updated it 
to the new build scheme (using Python distutils) yet. As it is, it can 
only be compiled with Python 1.5 using "compile" followed by "install" 
in the folder addons/MMTK_SparseModes. The file arpack_real_sym.c from 
ARPACK is included.

I guess I should update this to distutils and put it on the server, but 
I first have to check if redistribution of ARPACK files is allowed.
