I think you will have to replace the form at line 250 in "guix/build-system/asdf.scm": --8<---------------cut here---------------start------------->8--- (lisp (default-lisp (string->symbol lisp-type))) --8<---------------cut here---------------end--------------->8--- by something like: --8<---------------cut here---------------start------------->8--- (lisp (default-lisp (match lisp-type ("sbcl" 'sbcl) ("ecl" 'ecl) ("clasp" 'clasp-cl) (_ (error "The LISP provided is not supported at this time."))))) --8<---------------cut here---------------end--------------->8--- This 'lisp' variable is used a little lower in the 'build-inputs' field at line 266.
