Unless I am missing something, the question to be answered is if Guile requests opening modules using a name like "module.so" (assuming a particular naming scheme), "module.la" (using libltdl as originally intended), or bare "module" (using libltdl heuristics, which tries several incantations, such as looking for .la, and .so).

On the Bug-Guile list, Ludovic Courtès said it was the last one , specifically the code in 'ibguile/dynl.c', which looks like:

static void *
sysdep_dynl_link (const char *fname, const char *subr)
  lt_dlhandle handle;
  handle = lt_dlopenext (fname);
  if (NULL == handle)
      SCM fn;
      SCM msg;

      fn = scm_from_locale_string (fname);
      msg = scm_from_locale_string (lt_dlerror ());
scm_misc_error (subr, "file: ~S, message: ~S", scm_list_2 (fn, msg));
  return (void *) handle;

OS-X's module loading does not care about the file extension.

So from what you say, the problem may simply be that .dylib isn't in the list.
