Well, for example on linux the static dlopen does not work either, but
the statically linked binary is able to make use of a shared libc/libdl
at runtime and use its dlopen.  I don't think the BSDs do anything like
this, but I'm not sure.  Best would be if somebody tried this.  (I just
tried FreeBSD, it does not work, as expected.)

Nobody is saying the BSDs should be doing anything different, I think.
This is a bug in Libtool/libltdl, only I'm not yet sure about how to fix
it properly.

Thanks for the pointers,
