Chris,

I'm CCing this to the guile mailing list, because I'm afraid I can't
be of any real help myself.

I have only recently written a little text about how dynamic linking
works within Guile, and how to combine it with the module system.
This is probably not what you are asking for.

Soo, could you show us a small Scheme program that does not behave the
way you expect it?  I guess you have trouble with something like this:

    (define-module (my-module)
      :use-module (ice-9 slib))

    (require 'posix-time)
    (display (ctime (current-time)))

Could you try to run this with "guile -s" for starters?
