Hi, Please fix debbugs #647544: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=647544#10 I reported it on debbugs but actually it's from upstream. In brief, what's the return value of this? (subpathname "/usr/share" "common-lisp/source/") I think it should be "/usr/share/common-lisp/source/", not "/usr/common-lisp/source/". Thanks, Des
