Oops, sorry.  Could you try the following patch?

The real problem is that there is a hard-coded path in module.scm:

(define *root-package*
  (make-multi-package '("/usr/local/share/guile/site")))

But since we are not going to use my module system, we can omit
this entirely.  I'll apply a better solution some time later.

Both.  If you throw an exception to the VM, it goes through it.
