I've inherited a project on a hosted server and I'm trying to install and import numpy and nltk into the project. The OS is centOs 5.10 and the web app uses web.py. There are two version of python installed on the box both python 2.4 and python 3.3. The default is pointing to version 2.4, "python -V" = python 2.4.3. Eventually I will upgrade and use python 3.3, move toward Django, etc but for the time being I'm stuck with this setup. I've been researching a while on how to do this. From my research I've read about using pip to install numpy and then nltk. In the python2.4 directory I was able to use easy_install to install pip-1.4.1-py2.4.egg. When I try to use pip-2.4 to install anything I get a syntax error in the pip file. See below...

Doing some research it's seems this error comes from the fact that I have multiple python installs. This lead me to install virtualenv-1.10.1-py2.4.egg in the python2.4. But when I try to run virtualenv I get the following error.
ERROR: this script requires Python 2.6 or greater.
I've also tried to install numpy using python2.4's easy install but that errors out as well.

Again I don't want to upgrade or change the version of python. In the python3.3 directory I was able to successfully run virtualenv. I was hoping this would correct any dependency issue that I might be having because of the multiple installs, but it hasn't. My plan right now is to try and get virtualenv to successfully run for the python2.4 version. My hope is that if I can set up virtual environments for both versions of python it will resolve the problem. But as you can see I can't get virtualenv in python2.4 to successfully run. Below is some more information about what is in each python directory.
[user@server python3.3]$ ls
easy-install.pth nltk-2.0.4-py3.3.egg numpy-1.8.0-py3.3.egg-info PyYAML-3.10-py3.3-linux-i686.egg

There is a lot of stuff out there for this and I've been researching for a while. Any help is greatly appreciated! Thanks!
