Comment 5 for bug 254035

On my sid workstation ('fluxx'), I did the following commands, and observed
setuptools download nevow from divmod.org, despite nevow-0.9.31 already being
installed such that 'import nevow' worked inside a python shell.

{{{
HERE = ~/trees/tahoe-mutable-205-312/t

go:
 mkdir -p $(HERE)/tmp/lib/python2.4/site-packages
 PYTHONPATH=$(HERE)/tmp/lib/python2.4/site-packages easy_install --prefix=$(HERE)/tmp nevow
}}}

I will see if I can find a machine on which this same test does *not* download anything, and then compare the setuptools/easy_install installations.
