As long as dlopen's search paths are properly setup, I don't think you
need to load dependent libraries explicitly in any Lisp.

How about providing this search as an interactive restart when loading
via plain dlopen() fails?

BTW, loading libraries via absolute paths is usually wrong, since it
defeats dlopen()'s search capabilities. This is something we should
probably warn about in the User Manual. Created an issue to track
that: <https://bugs.launchpad.net/cffi/+bug/1303302>.
