The problem is, this has false positives. If
/usr/local/lib/pythonX.Y/site-packages (or dist-packages on Debian)
doesn't exist, it won't be in sys.path, but *will be* once it exists.

You could try to address this by creating the directory before checking.
However, you shouldn't be creating things on the system as part of the
configure check. Even if you tried, it won't work for prefix=/usr/local
unless someone uses `sudo` for `waf configure`.
