It can. However, I encountered the problem on Linux/x86, and I don't  
get quite as far along when trying it on my Mac:

;;; Loading "/usr/local/asdf-install/site-systems/closer-mop.asd"
; registering #<ASDF:SYSTEM #:CLOSER-MOP 21048680> as CLOSER-MOP
keyword list is not a proper list
Broken at ASDF::PARSE-COMPONENT-FORM.

That could be caused by any number of local things, though, and I  
haven't tried to diagnose it yet.
