Yum won't show it. (Yum is an OS-level package manager, easy_install is a
python-level package manager)

Hmm. If you're absolutely sure that it's python2.7 that you're running, I
would get out the big hammer. Got to
/usr/local/lib/python2.7/site-packages, and rm(dir) anything related to
psycopg2. Then look in any "*.pth" files and delete lines related to
psycopg2. Then try re-running easy_install.

You would definitely need the -devel packages for PG because easy_install
is trying to compile a C module. But I've done the same thing before
(tried to install psycopg2 w/o the devel package installed), and just an
ordinary re-run fixed it for me.
