Thank you Ned,
but I can't find environment variable name on that page which is
equivarent to '--install-scripts' or other options.
$PYTHONHOME seems equivarent to --prefix option, but the following
reports error.

  $ mkdir -p local/lib/python2.7/site-packages
  $ PYTHONHOME=local python setup.py install
  ImportError: No module named site
