Building 0.8.4 standalone

Hi

I'm trying to compile 0.8.4 window manager from 
matchbox-window-manager-0.8.4.tar.gz. My configure options 
(--disable-xft --disable-png --disable-keyboard --enable-standalone 
--x-includes=/usr/X11R6/libs/ --disable-ping-protocol --with-x) result 
following notes from ./configure:

Looks good. However, the make process fails:

Am I missing something?
