Dear ASDF hackers, my experimental repository at http://common-lisp.net/gitweb?p=projects/xcvb/asdf.git contains some (fugly) code to address the configurability issue: https://bugs.launchpad.net/asdf/+bug/485918 I won't release the code until I clean it up somewhat, but I'm already requesting comments. The idea is that you should configure your paths through user and system files, more or less as described in a previous mailing-list post: http://common-lisp.net/pipermail/asdf-devel/2009-December/000580.html This hooks into the asdf sysdef search mechanism in a way that takes precedence over the current *central-registry* but falls back to it when systems are not found.
