dear sir/madam:

One problem occured when we tried to practise a CGEN project. We followed 
the the manual(http://sources.redhat.com/cgen/docs-1.0/cgen_5.html#SEC162):

1.Run guile. 
2.(load "dev.scm") 
3.Load application, e.g. (load-opc) or (load-sim) 
4.Load CPU description file, e.g. (cload #:arch "m32r") 
5.Run generators until output looks reasonable, e.g. (cgen-opc.c).

We succeeded in the first two steps, but when we input (load-opc) or 
(load-sim) in guile, it ouput the following information:

guile> (load-opc)
Skipping slib/sort, already loaded.

Backtrace:
0* [load-opc]
1* [load "read"]
2  [primitive-load-path "read"]
3* [maybe-load "slib/pp" #f pretty-print]
4  (letrec ((dynamic-func? #)) (let (#) (cond # # #)))
   ...
5  [primitive-load-path "slib/pp"]
6* (require (quote generic-write))

/usr/share/guile/slib/pp.scm:3:1: In expression (require (quote 
generic-write)):
/usr/share/guile/slib/pp.scm:3:1: Unbound variable: require
ABORT: (misc-error)

We wonder how to solve this problem, would you please give us an answer, 
thanks!
