Ah.  I think you need to do exactly what the error message says and
rebuild Octave's libraries as shared libraries.  Configure with
--enable-shared and things will probably be a bit better.

The reason that it appeared to succeed with gcc is that gcc does not
automatically link with libstdc++.  But that library is required, (and
apparently required to be a shared library) so you have simply delayed
failure until you try to load the .oct file.
