Line 25, hunchentoot:client-as-string gets called and calls (Line 22) 
usocket:hbo-to-vector-quad. And that _is_ strange because the only call
into usocket from client-as-string is usocket:vector-quad-to-dotted-quad
which does _not_ call any usocket code. Where does that call come from?

Next strange thing:

1 Invalid program: Can't bind or assign to constant SECOND.

That seems to be the error that get's triggered from within usocket:hbo-to-vector-quad

 (defun hbo-to-vector-quad (integer)
  "Host-byte-order integer to dotted-quad string conversion utility."
  (let ((first (ldb (byte 8 24) integer))
        (second (ldb (byte 8 16) integer))
      ....

Why should usocket:second be defined as a constant here? There _is_ no symbol 'second in
the usocket package.

The problem is that I cannot even start to debug, because only a criptic message is written on the terminal and then nothing more. Note that the application still works without any problem in mac os x (even after the update of the quicklisp packages: #:hunchentoot #:ht-simple-ajax #:cl-postgres #:simple-date #:html-template #:cl-who #:do-urlencode).
