[pptp-server] PPTPD under NetBSD: pptpd conflicts with gre device

[Simson L. Garfinkel]

Darrin,

Thanks for your help. That was the problem! When I removed the gre device, pptpd
started working properly.

Now to get Samba working over the PPTP connection, and to get CHAP-80 in place.
Shouldn't be too hard....
