[Mark Evenson]

let-plus-20110730-git, a dependency for LLA, cannot be compiled resulting in the following error:

Test:

(ql:quickload :plus)

[Mark Evenson]

(ql:quickload :let-plus)

[ehuelsmann]

Compilation failure fixed by replacing compiled code with the original form.

However, a condition should be signalled to the user; that's the work left to do here.

[ehuelsmann]

Quicklisp correctly reports "Unable to compile macro DEFINE-LET+-EXPANSION."

I guess the work here is done.
