[Q] how can i run cgen interactively?

[ml]

hi, i'm a student of graduated school of Univ. in japan.
i'm trying to port gnu tool-chain to our new processor with cgen.
but i cannot run cgen interactively. how can i run it?
i'm trying to port Binutils-2.16.1 and GDB-6.2.

my environment is 
  OS:    Debian GNU/Linux 3.1 sarge (stable)
  CGEN:  cgen-20051015
  Guile: guile-1.6.7

i run cgen as followed. now i running cgen with m32r.

$ tar xjf cgen-20051015.tar.bz2 
$ cd cgen-20051015/cgen/
$ guile
guile> (load "dev.scm")
guile> (load-opc)
guile> (cload #:arch "m32r")
guile> (cgen-desc.h)

Backtrace:
./desc-cpu.scm:1002:32: In expression (opc-file-path):
./desc-cpu.scm:1002:32: Unbound variable: opc-file-path
ABORT: (unbound-variable)

could you please tell me how to run cgen interactively.
i found that opc-file-path is defined in cgen-opc.scm, so i tried to load it.
but i cannot load it.
