you can put arbitrary python code in setup.py. so before you call setup()
in the file, put something like:

import subprocess

try:
    version = subprocess.check_output(['/usr/bin/ovftool','--version'])
except subprocess.CalledProcessError:
    print "ovftool is not properly installed"
    raise
if not is_this_the_right_version(version):
    raise ValueError("ovftool is not the right version")


of course, you'd probably want better error messages, etc, but hopefully
you get the idea.
