The 2.2-3 RPM from python.org does "./configure --prefix=/usr" (unless you enable the pymalloc or ipv6 flags before building, the RPMs up there do not). It then does "make".

About the only thing that may be unusual would be that RPM may automatically strip the resulting binary. I'm not doing it manually.

Interesting that you're seeing oddness. Note that if you download the SRPM, you can install the .src.rpm and then build it by doing:

rpm -bc /usr/src/redhat/SPECS/python-2.2.spec

(or other similar location that the spec file would be installed depending on your distribution). Also note that you can have it build a patched version by adding the patch below the "Patch1:" line as "Patch2:", and also add a line below "%patch1" which reads "%patch2" (unless you have to give options such as "-p1" -- see the example for "%patch0"). You can then do a fresh build of the code using the above command. You can also build an RPM by using "rpm -ba [...]".

One of the big wins with a packaging system -- reproducability...
