Thanks for the suggestions. I had stopped Apache, and I also tried a fresh
install in a new virtualenv.
That actually helped me discover the root cause of the problem because I
got a different traceback during a fresh install. Pasting it here in case
others run into the same problem someday:
(syt_env)[syt_admin@VM1 vishwaas]$pip2.7 install -r

It turned out to be a known issue with pip version 7.1.2. I need to upgrade
to the latest pip version 8.0.2
https://github.com/pypa/pip/issues/2674
https://github.com/pypa/pip/issues/3245
Meanwhile, the workaround is to use the option --no-cache-dir
(syt_env)[syt_admin@VM1 vishwaas]$ pip2.7 install -r
requirements/production.txt --no-cache-dir
This worked fine, and I was able to upgrade the packages in my old
virtualenv as well as do a fresh install in the new one.
Whew!!

Tanuka
