Although not specific to your problem, I recall that a while back CMUCL
accepted (at one time maybe even required) vectors for directories in
pathname functions.  There may be some relics of code that handled that
particular idiosyncrasy.  It may be sufficient just to change the type
of the directory list from vector to list in order to solve the problem.

I recall this from some work I did porting defsystem.lisp to other 
platforms.
As I now look at the sources, it does, indeed, appear to be a 
problem with
the defsystem code.  One quick fix to try would be to push the 
:cmu17 feature
*features* and see if that fixes things:

     (push :cmu17 *features*)

It should fix the defsystem part.  What I'm not sure about is 
whether adding
that feature will break anything in CL-HTTP.

A better long-term strategy might be to get a more recent version 
of defsystem.lisp.
IIRC, Marco Antoniotti has been working on upgrading that 
particular facility.
I don't know if this has been addressed in more recent versions.  
The latest version
I looked at still had the code only conditionalized for cmu17 and 
not cmu18
