The "let", to define the org variables, ends up putting the "import"
inside the scheme expression, like this:

      ;; -*- geiser-scheme-implementation: guile -*-
      (let ((x '1)
            (y '2))
      (import (except (rnrs base) error vector-map)
               (only (guile)
                     lambda*
                     λ)
               ;; let-values
               (srfi srfi-11))

      (let-values ([(a b) (values x y)])
         (simple-format #t "~a ~a\n" a b))
      )


which raises an error when evaluated the first time (the second time,
the "import" has already imported the new "let-values" feature
(srfi-11), so, the evaluation works). You can test this manually in a
guile session.

I guess you'll have to use sessions, and do the "import" in a separate
block first.
