Obviously you should be using IPSec if at all possible, but a lot of OpenBSD hackers have to use PPTP on networks they don't control. In a helpful misc posting, qstreb posted a
for getting connected via PPTP. Note that you'll have to recompile your kernel and probably do some updating for the PF rules. However, this seems like a good place to start.
Note that the PPTP toolkits may not be very stable, but it's something (and maybe you can even improve upon it). Also, PPTP has known security vulnerabilities, this is only for situations where you have to use it. If you have any better documents, feel free to share them.
