There is at least an inconsistency in SBCL's TRUENAME: it only
resolves the "topmost" symbolic link.  So, given
  /tmp/foo (directory)
  /tmp/foo/zot (file)
  /tmp/bar (symbolic link to /tmp/foo)
(truename "/tmp/bar/zot") returns #p"/tmp/bar/zot", not
#p"/tmp/foo/zot".  Whether this is an outright bug in TRUENAME
(unlikely, given the flexibility the CL pathname standard affords
implementors ;-), a suboptimality that we want to correct, or a
bad implicit assumption that ASDF has erroneously made, I don't know.

From here, we see that it has failed to fully resolve the path for
clx.asd.

Cheers,
