If no one else can reproduce this I suppose there's no point leaving it open, but it's still present for me using Python 2.7.1:

% bzip2 -dc Python-2.7.1.tar.bz | tar xvf -
% cd Python-2.7.1
% CC=cc CXX=CC CPPFLAGS='-I/usr/sfw/include' LDFLAGS='-L/usr/sfw/lib -R/usr/sfw/lib' ./configure --enable-ipv6 --prefix=$HOME/pytest
% gmake -j5
% gmake install
% $HOME/pytest/bin/python
