Thanks a lot for the reply, in my case I'm guessing it's the first case. 
I don't use sb-rotate-byte in my code directly, but two of the libraries 
that I'm using use it. One is ironclad, and the .asd file looks normal 
enough - I can see this in defsystem:

#+sbcl :depends-on #+sbcl (sb-rotate-byte)

But the other library, cl-utilities uses this in it's .asd file:

;; Sometimes we can accelerate byte rotation on SBCL by using the
;; SB-ROTATE-BYTE extension. This loads it.
#+sbcl
(eval-when (:compile-toplevel :load-toplevel :execute)
  (handler-case (progn
          (require :sb-rotate-byte)
          (pushnew :sbcl-uses-sb-rotate-byte *features*))
    (error () (delete :sbcl-uses-sb-rotate-byte *features*))))

My lisp-fu is not advanced enough to see if the latter is a problem, but 
could there be a problem with it? If yes, how can I fix it?

Thanks much,
Vamsee.
