hmm -- usually it's pretty straightforward on Linux (except maybe
getting an optimized LAPACK, which you may or may not need).

I'll leave that for the next step.

yup -- many of the Linux package systems split the stuff you need to run
Python code from what you need to compile stuff against it -- common
with other libs, packages as well.

Ahh -- a different story -- AFAIK (and I'm NOT an expert) the distro's
packages will install python into system directories -- if you really
need each user to have their own install, you may need to install from
source. That should be pretty straight forward, too. Get the source
tarball from python.org, and follow the build instructions. You'll need
to specify a user install in that process somehow.
The latest numpy should work with any recent python -- If you are free
to choose, use 2.7.1 -- it's the latest production version of the 2.*
series. 3.* is still a bit bleeding edge. YOU can grab the tarball here:
Once you've got a python working, a simple "python setup.py install"
should do for numpy.
