ASDF:MAKE is a shorter synonym for ASDF:LOAD-SYSTEM as far as I =

Probably not:  you really want to depend on the ASDF encapsulation of =
JNA in 'contrib/mvn/jna.asd=E2=80=99, not the presence of yet another =
special (=E2=80=9C*jna-loaded*=E2=80=9D).    Since you are requiring =
ABCL-ASDF:RESOLVE to be present, you can make the assumption that both =
ASDF and ABCL-CONTRIB have been successfully REQUIREd.

Alright.  I will try to take a stab at this after I figure out the way =
