Nico,

We haven't been using the mod_lisp construction for a long time, but  
it should still work. A recent change to #'START-KPAX switched the  
default argument for :server-class from 'mod-lisp-server to 's-http- 
server (see previous sentence, sorry for the inconvenience). That  
could be your problem (if you are tracking the darcs repo), but you  
do get a mod-lisp-server instance.

You could also do the following:
- do a describe of the mod-lisp-server instance so that we can look  
inside it (do the ports match ?)
- check all apache log files (error and access)
- can you see/inspect/debug anything on the lisp side ?
- telnet manually to lispworks and talk the mod_lisp protocol
- check your firewall settings (you are running both servers on the  
same host ?)

It will probably be a very simple configuration fault, but these  
things tend to be hard to find...
