ECL requires asdf-ecl.lisp to work properly

I'm trying to make quicklisp work with my pre-existing install (which works for 
sbcl, ccl, etc). I get an error when trying to load the client                  
(version 2011040600).                                                           

This is a newly compiled ECL 11.1.1 (no special configure flags) on Mac OS X    
(Xcode 4).                                                                      

...                                                                             
;;; Loading "/Users/elliott/quicklisp/asdf.fas"                                 
ASDF could not load sockets because Error while trying to load definition for   
system sockets from pathname /opt/local/lib/ecl-11.1.1/sockets.asd: No          
applicable method for SOURCE-FILE-TYPE with arguments of types                  
 COMPILED-FILE                                                                  
 PREBUILT-SYSTEM.                                                               

The problem goes away if asdf-ecl.lisp is loaded at the same time Quicklisp's asdf.lisp is loaded.

Backed off the required asdf version to 2.011 to avoid this problem.

Looks like we still have this problem with ECL

Any idea? I am running ECL 12.7.1 in a MacOS 10.8.2.

I think this problem will go away in the next ECL release. I'll leave this open until it is resolved one way or another.

This problem should be solved now that ECL uses ASDF 3 — can you check?

(Alternatively, it should be solved when Quicklisp uses ASDF 3.)
