In config/python.m4 you'll find the following:

# threaded python is not supported on bsd's
AC_MSG_CHECKING(whether Python is compiled with thread support)
pythreads=`${PYTHON} -c "import sys; print(int('thread' in
sys.builtin_module_names))"`
if test "$pythreads" = "1"; then
AC_MSG_RESULT(yes)
case $host_os in
openbsd*|freebsd*)
AC_MSG_ERROR([threaded Python not supported on this platform])
;;
esac
else
AC_MSG_RESULT(no)
fi

So it looks like we throw that error on OpenBSD and FreeBSD. That was
apparently introduced by this relatively inexplicable commit, back in
2005:

http://git.postgresql.org/gitweb?p=postgresql.git;a=commit;h=d3a0c8dce9380e77734e41becd9aa35618030352

It seems plausible this might not be a problem any more, 5 years on...
perhaps you could comment that test out of configure and see if it
works for you. Or if not, what the actual problem is.
