Bug on Windows: A required privilege is not held by the client

Version: 0.8.2
Simply running: pip2pi /pip2pi -r requirements.txt results in this error:

This is very likely because of the security policy on my laptop that disallows symlinks.

I don't know if it there are any negative consequences to this, but I would fall back to a copy if a symlink fails.
