install python 2.6 on Ubuntu 12.04

[Dan Stromberg]

If the pythons you require are in synaptic (sudo to root and run synaptic),
you probably can just use them.

If not, then you, for each release, need to:
1) download a tarball using a browser or whatever
2) extract the tarball: tar xvfp foo.tar.bz2
3) cd into the newly created, top-level directory, and run ./configure
--prefix /usr/local/cpython-2.6 (or similar)
4) Run "make", optionally with parallelism; I often use number_of_cores+1,
so for a quad core system, I might use "make -j 5".  This speeds up the
build.
5) Run /usr/local/cpython-2.6/bin/python - just to make sure it gives a
prompt.  control-d to exit.
6) Try running your script with one of your new python builds:
/usr/local/cpython-2.6/bin/python my-script

I've done this for 2.5, 2.6, 2.7, 3.0, 3.1, 3.2 and the 3.3 preview stuff.
They cooperate with each other well.  Actually, I scripted out the build so
that I'd get all 7 built automatically with cython and pylint in them.
