Comment(by pgj):

 Replying to [comment:6 kazu-yamamoto]:
 > The build and installation works well with your first patch (only).

 Great!

 directory.

 Yes, as I noted in my previous comment, this is because of a bug in
 `rtld(1)`.  If you want to see this working, you can experiment with a
 [http://people.freebsd.org/~pgj/patches/2013/04/15/rtld-releng91.fix.diff
 fix] (written by Kostik Belousov).  Download the diff, and rebuild your
 `ld-elf.so.1` from the base system source code.  This should be under
 `/usr/src/libexec/rtld-elf`, where you should just apply the patch and
 reinstall the dynamic loader by issuing the following commands below.

 {{{
 # make
 # make install
