I did.  Apparently the problem was indeed that the atlas installation on 
our systems
is outdated.  (Like almost all other software that is managed by the 
system group ;-) )

Installing the atlas binary in some directory dir/ and pointing both 
and ATLAS environment variables to dir/ worked.  Now everything runs 

(I tried installing the binary myself before but this didn't work.  This 
will probably also
have been due to not setting LD_LIBRARY_PATH.)

Now the output of python -c 'import atlas_version' is

ATLAS version 3.6.0 built by pearu on Sun Apr 11 01:13:26 EEST 2004:

which looks like it is what it was supposed to be...

Thanks for the patient help!  I would never have done this on my own!
