error starting server in MCL

I have been unable to start cl-http-70-23a in MCL.  I have tried under Mac OS 8.6 and Mac 9.2.  I am attempting the stand-alone configuration, as described at http://wilson.ai.mit.edu/cl-http/configure.html , using MCL version 4.3.1, but have also tried MCL 4.2.  I am working on a PowerPC 9600, but have had similar problems on a PowerBook G4.

Under MCL 4.2, when I load the file "start-server-appletalk.lisp", I get:

;Loading #P"ag:MCL 4.2:cl-http-70-23a:mcl:start-server-appletalk.lisp"...
;Loading #P"ag:MCL 4.2:cl-http-70-23a:mcl:mcl-configuration.lisp"...
;Loading #P"ag:MCL 4.2:cl-http-70-23a:mcl:envdcl.lisp"...
;Loading #P"ag:MCL 4.2:cl-http-70-23a:mcl:translations.lisp"...
> Error: Too many arguments (no opt/rest)
> While executing: REMOVE-STRUCTURE-DEFS
> Type Command-. to abort.

The error above ccurs when the last line in the file "envdcl.lisp" is loaded: (load-standard-systems).

Trying the same thing in MCL 4.3.1, I get:

#<Package "COMMON-LISP-USER">
;Loading #P"ac:Lisp:cl-http-70-23a:mcl:mcl-configuration.lisp"...
#P"ac:Lisp:cl-http-70-23a:mcl:mcl-configuration.lisp"

and the error occurs again at (load-standard-systems).  Since the variable $KTCPNAME was unbound, I tried evaluating (require :opentransport) before loading the file "start-server-appletalk.lisp".  When I did this, I got warnings that all of the variables in open transport are being redefined, and then ...
...

Can somebody help?  CL-HTTP looks like a fascinating tool, but I'm stuck at first base!
