What does this have to do with Python? It's CentOS (and Red Hat's)
decision not to provide a package for Python 2.7. It's not feasible
for the Python community to provide a repository for each of the 200+
Linux distributions. The instructions for building Python are exactly
the same as to build any other large project and there is absolutely
nothing that we can do about that- you can't compile a program without
a compiler and you can't link to other programs without the
development headers. You'll have the exact same problems if you want
to install gcc 4.6.2 unless some 3rd party has decided to build the
rpm for you.
