Ok... After initializing Quicklisp and ASDF, I do:

  (setq asdf:*immutable-systems* (uiop:list-to-hash-set "gendl" ... ))

as well as

 (asdf/find-system:register-preloaded-system "gendl")
 ...

with all the known preloaded systems.


But now if I do

  (ql:quickload :gendl)

I still get this error:

   "Requested system gendl is in the *immutable-systems* set, but not
loaded in memory"

Apparently,

   (asdf:system-registered-p "gendl")

is still coming back as NIL.

Is there another step I should be doing?
