Saving core with matlisp

Hello.

I have run across another problem.  I want to save a core including Matlisp
and Femlisp which I do using

(ext:save-lisp "/home/neuss/FEMLISP/bin/femlisp-core" :site-init NIL
               :print-herald t)

When I use this core I get the error message:

---------------------------------------------------------------------------
Undefined foreign symbol: "dcopy_"
   [Condition of type KERNEL:SIMPLE-PROGRAM-ERROR]

Restarts:
  0: [ABORT] Return to Top-Level.

Debug  (type H for help)

(KERNEL:UNDEFINED-FOREIGN-SYMBOL-ERROR-HANDLER "<error finding name>"
                                               #.(SYSTEM:INT-SAP #x3FFFCA50)
                                               #<Alien (* #) at #x3FFFC6E8>
                                               (14))
Source: Error finding source: 
Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no longer exists:
---------------------------------------------------------------------------

Does anyone know what is the problem here?

Thanks, Nicolas.
