I was going to chime in with this anyway had the thread said nothing; I
strongly prefer to specify --prefix explicitly with configure.

My personal habit to to build with (adjust to match):

  --prefix=/usr/local/python-2.6.4

and put some symlinks in /usr/local/bin afterwards (python2.6, etc).

That way one doesn't tread on the system Python (after all the OS vendor
distro is also a collection of packages with coordinated versions)
and one can easily put in another python beside it.

Indeed. And this is a strong reason to keep out of the vendor's /usr
filesystem space, also.
