Fails on ABCL-1.9.2

[catap]

It fails as:

:info:build Caught UNBOUND-VARIABLE while processing --eval option "(asdf:operate (quote asdf:build-op) (quote 3bmd-tests))":
:info:build   The variable DEF-GRAMMAR-TEST is unbound.
:info:build Command failed: env XDG_CACHE_HOME=$HOME/.cache /opt/local/bin/abcl --noinit --batch --eval '(require "asdf")' --eval '(setf asdf:*central-registry* (list* (quote *default-pathname-defaults*) #p"/opt/local/var/macports/build/_Users_catap_src_macports-ports_lisp_cl-3bmd/cl-3bmd/work/build/system/" #p"/opt/local/share/common-lisp/system/" asdf:*central-registry*))' --eval '(asdf:operate (quote asdf:build-op) (quote 3bmd-tests))' 2>&1

SBCL, ECL, CLisp and CCL works.
