I want to share how i compiled from source python versions 2.4 and 2.6 on precise pangolin. These versions of python where discarded on this ubuntu release, they can be compiled from source with just few quirks.
I am not completely sure about the required libs since i tried various combinations before looking at the actual code, so any comments on those are well accepted 
python 2.6.8
required libs:
Code:
apt-get build-dep python
python source download:
exctract
Code:
tar xjvf Python-2.6.8.tar.bz2
cd Python-2.6.8
create a text file setup_py.patch with any preferred text editor (vim anyone?) with the following content:

apply the patch:
Code:
patch Modules/_ssl.c < _ssl.patch
launch the ./configure command with the following syntax:
Code:
env CPPFLAGS="-I/usr/lib/x86_64-linux-gnu" LDFLAGS="-L/usr/include/x86_64-linux-gnu" ./configure --prefix=/opt/python2.6
be careful: the previous command will set the installation directory on /opt/python2.6. If you want to change that directory you have to change the --prefix parameter
