Problems compiling latest CVS version

I downloaded matlisp from CVS today.
I configured with

./configure --with-lisp=cmucl --with-lisp-exec=/home/rif/Software/CMUCL/bin/lisp --prefix=`pwd`

and then tried a make, but I get the following error when CMUCL tries
to load matrix.x86f:

; /home/rif/Software/matlisp/bin/matrix.x86f written.
; Compilation finished in 0:00:01.
;; Loading #p"/home/rif/Software/matlisp/bin/matrix.x86f".


Error in function PCL::FIND-CLASS-FROM-CELL:  No class named: REAL.

Restarts:
  0: [CONTINUE] Return NIL from load of "/home/rif/Software/matlisp/bin/matrix.x86f".
  1:            Return NIL from load of "start.lisp".
  2: [ABORT   ] Skip remaining initializations.

Debug  (type H for help)

Any suggestions?

Cheers,
