I have installed sbcl and cmucl... Unfortunately sbcl finds
/usr/share/common-lisp/source/cmucl/clx/clx.asd - it does not compile
and it should not attempt to do so in the first place. I have played
around with ASDF2 configuration for some time, but I am unsure how to
resolve this. My goal would be that everything under
/usr/share/common-lisp/source/cmucl/ is invisible to sbcl.
How can I resove this?
