I just ran into the same problem with sources from today (March 29,
2005).  I was able to work around it with
`bmake LDFLAGS=-pthread`

It seems to be a problem with unresolved pthread_* symbols in
librfuncts, which are resolved when using the -pthread flag.  I'm
using DragonFlyBSD, but use whatever linker flags are needed to
include thread linkages for your compiler as the value of the LDFLAGS
variable.
