Loading multiple versions of a Module

Guile currently doesn't allow loading multiple versions of a Module. For
example this will not work.

--- start.scm
(import (a) (b (2)))

--- a/a.scm
(library (a)
  (export helloA)
  (import (rnrs) (b (1)))
  (define helloA (lambda ()
                  (display "hello from A1\n")

--- b1/b.scm
(library (b (1))
 (export helloB)
 (import (rnrs)))

(define helloB (lambda ()
                 (display "hello from B1\n")))

--- b2/b.scm
(library (b (2))
 (export helloB)
 (import (rnrs))
 (define helloB (lambda () (display "hello from B2\n"))))

Is there are away to get around this? What is the reason for this
behavior? Is it part of r6rs or something?
