no. these things should really be handled by distribute (or
setuptools/distutils). there is nothing special about the py.test
script. just imagine a world where every python package X came with a
custom X_INHIBIT_VERSIONINSTALL environment variable. 

If you really like it that way, try to persuade the distribute guys to
implement that feature (probably with a switch in ~/.pydistutils.cfg)
