Hello. In the current head, SBCL 1.0.43.13 fails on swank-loader.lisp, when ASDF is not afailable. The reason is that (find-symbol "COMPILE-FILE-PATHNAME*" :asdf) signalls error "Unknown package :asdf). Another error is loading contrib swank-asdf by presense of SBCL or ECL: #+(or asdf sbcl ecl) swank-asdf Even if SBCL is boundled with ASDF (which is not always the case), the feature :asdf will be afailable, and therefore it's sufficient to just have: #+asdf swank-asdf The patch is below.
