Hi,

The problem is that `(require (lib "load.ss" "slibinit"))' redefines
`require' to be the one defined by SLIB.

I don't know a good way around the problem. You could define
`mz-require' as an alias for `require':

 (module mz-require mzscheme
   (provide mz-require)
   (define-syntax mz-require
     (syntax-rules ()
       [(mz-require x ...) (require x ...)])))
 (require mz-require)

Then use `mz-require' instead of `require'.

That's ugly, but any solution is probably going to be ugly, since the
underlying problem is that SLIB doesn't use MzScheme's `module'.
