Building Maxima with Ecl 12.2.1 fails



Hello,

I'm trying to install Maxima (original 5.26.0) with the newest Ecl, 12.2.1, but
I get the following error:

;      - Loading binary file "binary-ecl/intl.fas" 
;;; Loading "/home/kullmann/OKplatform/ExternalSources/builds/Maxima/ecl/maxima-5.26.0/src/binary-ecl/intl.fas"
An error occurred during initialization:

          T)
 (COMMON-LISP-USER::BUILD-MAXIMA-LIB))
Unknown keyword :RENAME-AND-DELETE.
make[2]: *** [binary-ecl/maxima] Error 1

Any idea what this is?
