load(draw); broken in 5.23.0



Just upgraded from 5.21.1 to 5.23.0 on Slackware 13.0 x86_64 which comes with clisp-2.47.

load(draw); is now broken - it gives this error message:
?file_search1: grcommon.lisp not found in file_search_maxima,file_search_lisp.

I don't have a grcommon.lisp anywhere on my PC - what is it?

Looking into the source code of 5.21.1, 5.22.1 and 5.23.0, the first time 
grcommon.lisp is used is in 5.23.0:
grep -nR grcommon.lisp maxima-5.21.1 maxima-5.22.1 maxima-5.23.0
maxima-5.23.0/share/draw/draw.lisp:36:? (simplify ($load "grcommon.lisp")))

Anybody any ideas how to fix?

Cheers,
Peter
