Create a site.cfg file with the appropriate section; copy and modify
the site.cfg.example file.

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" ?

Can you give more information like the platform you are on, the full
path to this directory, the exact commands that you executed, and the
results of these commands?

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.

Rgds,
Amit
