Thanks a lot for your help. I will try with Anaconda.

If not with yum, I must have used easy_install or pip. I definitely did not 
build it from source.

Thank you,

Here is it is

numpy-1.4.1-9.el6.x86_64
package scipy is not installed

strangely it is saying scipy is not installed, but I did install it and I can 
import it in python..


So you installed scipy, but not from an RPM/yum. Sometimes packages installed 
manually put their files under /usr/libxx/pythonxx/site-packages and are mixed 
with packages from RPMs.
In the case of Centos 6, the versions of numpy and scipy are very old. As an 
alternative to the bundled Python installation mentioned before (Ananconda, 
Enthought) you can use Software Collections as explained here:

http://wiki.centos.org/AdditionalResources/Repositories/SCL
There is a python27 collection that ships numpy 1.7 and scipy 0.12, other 
packages such as matplotlib or pandas are not provided, so depending in your 
requirements the software collection may be useful or not.
