Christopher,

--prefix does not affect where Python stuff goes.
GDAL ./configure tries to detect Python location using sys.prefix 
property what is Python version dependent:

$python_prefix/$PYLIB/python${python_version}/site-packages


On x64 systems, PYLIB=lib64.

Here is the whole logic implemented:

http://trac.osgeo.org/gdal/browser/trunk/gdal/m4/acinclude.m4

If Python location can not be determined properly, then it falls back with:

pythondir='$(prefix)/lib/site-python'

Perhaps this last case is suspicious, but I'm not an expert of Python 
installations.

Anyway, if anyone has noticed bugs in the Python detection logic, please 
  don't hesitate to report a ticket at http://trac.osgeo.org/gdal/
