zacts on #guile has done work on a guile 2.0.11 package for FreeBSD
ports, and based on his reports it seems to work well.  IIRC, he built
it (and boehm-gc) with threads enabled (pthreads).  There was just one
notable issue: guile needs a patch (see attached) for clang 3.4 on
32-bit systems.  I haven't yet pushed this to git because it needs to be
made more portable.  Anyway, I doubt it's related to the problem you're
seeing.
