If you look at the "following -current" FAQ:
http://openbsd.rt.fm/faq/current.html
you will see that there has been a compiler change between your -current
and more recent -current systems.
I would "upgrade" with the latest snapshot, before attempting any source
builds. There have been recent changes in /etc, too... You can use
mergemaster to simplify and partially automate updates to /etc and /var.
Good luck!
