The same binary works on FreeBSD and OS X? Or is it a source-only gem?
If it is a source-only gem, is there a way to handle this with
extconf.rb instead? While OS X has FreeBSD roots, the two don't have
completely compatible internals, so its hard to describe this in

You should be able to hand-specify a platform with something like
Gem::Platform.new 'x86-freebsd', but there seems to be a bug.
Currently Gem::Platform is rather strict, as it is easier to make it
more permissive in future releases than less permissive in future
