FWIW, Faré provided a couple of new API functions to give ASDF users this function, notably SYSTEM-RELATIVE-PATHNAME and SYSTEM-SOURCE-DIRECTORY For what it's worth, I try to avoid logical-pathnames in portable code, having been hoist too many times on the petard of ACL/SBCL incompatibility in handling logical pathnames (SBCL sticks to the spec, in the name of portability and standardization; ACL accepts sensible, spec-defying logical pathnames in the name of utility).
