*Thanks again for the suggestions. It doesn't look to me like it's installed in /usr/local/lib/python2.7/site-packages. There's an egg directory there, but otherwise, no psycopg2. The egg directory doesn't mean it's installed, does it?? Here's an ls of that site-packages dir:*
Yes, an egg is just a zip file that at the destination may remain zipped or be unzipped into a directory:

*If I modify my sys.path, it still doesn't import psycopg2. The python command runs version 2.7.5 and you can see that in evidence in the sys path. It is looking at a different Python 2.7 that I installed under opt/bin and added to the PATH variable when I was trying to set up a virtualenvwrapper. *
So you have two versions of Python 2.7 in play, this complicates the issue.
*But I can't get psycopg2 to install to the 2.7.5 directory. Its site-packages is completely empty:* root@server [/usr/bin]# ls /opt/lib/python2.7/site-packages ./ ../ README
Probably because programs are being installed in the other version of Python 2.7
*whereas, /usr/lib64/python2.4/site-packages/ is full of stuff, including psycopg2. I've pasted just a small portion of the ls results below.*
It is the default Python and the one CentOS is using when it installs/updates Python.
*I also tried appending this path and importing. That gives a different error --tries to import it but fails, probably because it's inside a 2.4 install:*
That is correct Python 2.7 needs a version of psycopg2 compiled for it not 2.4.
Do you have other ideas?
Clean house. Uninstall the two versions of Python 2.7 you have and start over.
A bit of Googling found the below, it refers to CentOS 6 but is pointed to by people as useful on CentOS 5 also.
