This patch appears to fix the problem.  Just don't use --prefix.  It
doesn't seem to make any difference for python2.5, but it installs to
the correct place under python 2.6.

-- Alex

Install xen python modules to correct path under python2.6.

Do not use "--prefix" with setup.py scripts.  In python2.6 this causes
modules to be installed into /usr/lib/python2.6/site-packages, which is
not on the default python2.6 sys.path.

Without the --prefix option modules get installed to 
/usr/local/lib/python2.6/dist-packages, which is on the default python2.6 
sys.path.  If the installed version of python is python2.5, modules get
installed to /usr/lib/python2.5/site-packages, which is on the default
python2.5 sys.path.
