[elephant-devel] Defining a persistent class with a slot with an accessor invokes an error like "There is no class named CLASS-NAME."

[Tomo Matsumoto]

With the latest codes from darcs, defining a persistent class with a
slot with an accessor invokes an error like "There is no class named
CLASS-NAME.".

Here is an example.

(open-store '(:BDB "/path/to/db"))
(defpclass new-class () ((slot1 :accessor slot1)))

; There is no class named NEW-CLASS.
;    [Condition of type SIMPLE-ERROR]

Is that a bug in elephant?
I use SBCL 1.0.18 on Ubuntu Linux 9.04 32bit.
