I found a small issue with the :depends-on form for :drei-mcclim when trying to load the latest mcclim on clisp 2.41. Drei uses #. in :depends-on to try to define a dependency on swank if it's loaded. Unfortunately on clisp, this results in nil rather than no value. I'm seeing this error:
component NIL not found, required by #1=#<SYSTEM "drei-mcclim" #x19F581E9> [Condition of type ASDF:MISSING-DEPENDENCY]
There was discussion on c.l.l. about the behavior of the reader macro function in this regard, see the thread started by Pascal Bourguignon:

Note that I'm not actually trying to run drei on clisp, just trying to load mcclim.asd.
