install packages with pip to older Python versions

[Jabba Laci]

Hi,

I have Python 2.7 on my system. Today I wanted to try Google App
Engine but it runs on Python 2.5 at Google so I installed this version
on my machine next to v2.7 to avoid compatibility problems. However,
when I start the Python shell v2.5 and try to import something from
the GAE SDK (for instance "from google.appengine.ext import webapp"),
I get an error: "ImportError: No module named webob". (Note that with
v2.7 I don't have this problem.)

So, how can I install packages for a specific version of Python (here,
v2.5)? With 2.7 I use "sudo pip install <package_name>".

Thanks,

Laszlo
