Rudolf,

Thanks for figuring this out. I'll play with it one of the next days to see if 
I can come up with a guile 2.0 fix based on your findings.  One thing to keep 
in mind is that guile 1.8 should still be supported as well, so perhaps the 
eval-when (compile ...) constructs may have to be wrapped once again in guile2 
a guile2 only selector.
