Dear Ola,

I get an import error about "functools", which according to 
http://docs.python.org/2/library/functools.html is new in Python 2.5.

                                 ImportError at /

  No module named functools

The PYTHONPATH also includes '/usr/lib64/python2.6/site-packages' that 
is added along with the other environment variables, as shown in 
https://www.openmicroscopy.org/site/support/omero4/sysadmins/unix/server-install-linux.html.


On the web development server console it shows this:

Quit the server with CONTROL-C.

This discussion is about the same problem:

It seems I should leave python 2.4 as it is, and install 2.6 in parallel 
like it is now. And somewhere in the OMERO startup scripts I should 
replace "python" with "python26". Where could I do that?

Ok, this is good to hear. We can probably save the trouble of switching 
to Ubuntu, once we sort out the Python issue.


Best,
