Re: CLG-DISPLAY ?

(I've cc'd this message to Rick Taube, I think he's had some experience 
with CLG too).

Thanks, Andras, I appreciate your assistance. Alas, it doesn't work. I 
still end up with this error:

dlphilp@The3800:~/src/openmusic/OM-5.2.1/image/linux> sbcl --core om
This is SBCL 1.0.5, an implementation of ANSI Common Lisp.

This problem is quite vexing. No-one seems to have any idea what the 
variable is or does, and there is no information regarding it on Google. 
Still, it's only generating a warning, so perhaps it's not my real 
problem ? The error seems to be related to SLIME, not CLG.

At this point I'm completely stopped until someone can get me past this 
blockage. Any & all suggestions will be vastly appreciated. :)

Again, my system is running a 2.6.19 rt kernel, with SBCL 1.0.5 and CVS 
CLG. GCC is 4.1.2 under OpenSUSE 10.2.

PS: My apologies for being so dull-witted. Debugging Lisp is not 
something I'm at all good at...

Best,
