Problems in CL-STORE's use of FLEXI-STREAMS trying to run jfarm

[https://www.google.com/accounts/o8/id?id=AItOawkYnNNEAO_K40Gp0xROhyjOPgjvIskQ48M]

A installing [https​https://github.com/lmj/lfarm/blob/master/README.md lfarm] and using QL:QUICKLOAD to resolve dependencies, one encounters the following error:

The value #<FLEXI-STREAMS::VECTOR-OUTPUT-STREAM {64F9644E}> is not of type STREAM.
   [Condition of type TYPE-ERROR]

Narrowed the problem down to type declaration (which cl-store uses a
lot) & compilation. As an example:

(defun test (stream)

(declare ;; (type stream stream)

(stream stream)
;; (optimize speed (safety 1) (debug 0))
)

(write-byte 1 stream))

(flex:with-output-to-sequence (s)

(test s))

If you evaluate test (C-x C-e), the second form works. If test is compiled,
(C-c C-c), then the second form fails. Some sort of type check error? The
flexi-streams *is* a stream:

(block a

(flex:with-output-to-sequence (s)

(return-from a

(list (type-of s)

(typep s 'stream)))))

=> (FLEXI-STREAMS::VECTOR-OUTPUT-STREAM T)
