Hello.
collectors in quicklisp 2014-01-13 fails to build on ACL versions
where it was building OK previously.
The error is "Class #<COMMON-LISP:STANDARD-CLASS ACLMOP:FUNCALLABLE-STANDARD-OBJECT> is not yet finalized."
See test results of collectors on the last two quicklisp versions:
http://common-lisp.net/project/cl-test-grid/library/collectors.html
Clicking the error status in this report opens the build log.
