Strange that this incorrect call to print went unnoticed for so long...  You can't simply replace the call to print by a call to display.  The correct fix is:

                 port: port
                 (list version " 200 OK" eol
                       "Content-Length: " (u8vector-length message) eol
                       "Content-Type: text/html; charset=ISO-8859-1" eol
                       "Connection: close" eol

Thanks for reporting the problem!
