*I figured how to specify a particular installation of the libraries. I want
to do the opposite. How do I specify the following in site.cfg - "Don't
search for the library. Assume that it is absent and use the default slower
library" ?*

*I am installing this on a CENTOS linux platform (64 bit AMD opteron). The
path to my python directory is /home/amit/packages/Python-2.5.2 . If I
temporarily make the atlas library unavailable (by renaming the directory to
some name that is not in the path), I can perform the build. Now in the
installation stage, I use
python setup.py
and then choose the option 2/home/amit/packages/Python-2.5.2. In the
proposed sys.argv the path is shown as /home/amit/packages/python-2.5.2.
Incidentally, it also creates this new directory during install.
*Thanks Robert.
