I updated to r35212 and setting PATH=/usr/bin:/bin and PYTHON=/usr/bin/python on
our Centos 4 box everything worked fine.

I think we need to maintain compatibility with tools that build Subversion on
recent OSes. The fix in r35193, if not applied, would require the Subversion
packager to build Python and then Subversion. I think overall it's probably
less effort for us to do this work in one place then require anyone on an older
OS to build Python.
