Installing numpy on Red Hat 6?

python linux numpy installation rhel6

I'm trying to install numpy on a Red Hat (RHEL6) 64-bit linux machine that has Python 2.7. I downloaded and untar'd numpy 1.6.2 from Sourceforge, and I did the following commands in the numpy-1.6.2 folder:

python ./setup.py build
sudo python ./setup.py install #without sudo, this gives a permissions error.

Then, when I do import numpy on the Python prompt, I get ImportError: No module named numpy.

I read somewhere that numpy 1.6.2 is for Python 3.x, so I also tried the above steps with numpy 1.5.1, and I got the same ImportError.

I'm speculating that the solution lies in some environment variable gymnastics, but I'm not sure what files/directories Python needs to "see" that isn't in scope. Any suggestions for how to get numpy working?

I also tried some precompiled binaries for RHEL, but they gave various errors when I did sudo yum install [numpy precompiled binary url].rpm.

As an aside, my motivation for installing numpy is to use PyGnuplot. Also, I've installed numpy and PyGnuplot on other machines before, but it's been on Ubuntu and Mac OS.

RHEL6 ships numpy 1.4.1, see distrowatch. If 1.4.1 is new enough for you, you can install it with:

$ yum install numpy
