I believe that you are the first to post re this platform.  Since I
recently did FreeBSD 4 /i386 /alpha, I can offer some feedback.

Have you run `make check' in boehm-gc?  Likely, that will fail until
you are very close to a working port. (I did find one additional port
error related to memory mapping after having it "work".)  That is far
easier to debug than an application using X, etc.

If you had not done so, I also suggest verifying that non-threaded
boehm-gc `make check' works well first.
