 Hi, 
 
 Thank you for accepting my suggestion.
 
 However, I regret that libxcb still has runtime dependency on python
 via xcb-proto.
 It seems for me that libxcb can remove runtime dependency on
 xcb-proto, too.
 Libxcb itself installs C header files as well as libraries.
 Only two ports x11/libxcb and x11/xpyb explicitly depend on xcb-proto.
 Other ports, including ones which depend on libxcb,
 do not actually need any xcb-proto files, IMHO.
 
 I did an experiment and its result confirms my expectation:
 In a new jail environment, I installed x11/libxcb modifying its Makefile
 to remove runtime dependency on xcb-proto and python.
 Installed x11/libxcb and x11/xpyb, which are te only two ports
 which explicitly require xcb-proto.
 Pkg_delete'd xcb-proto-1.5.
 Then I installed some ports including x11/xorg-libraries, x11/xcb-util,
 graphics/cairo (which depends on xcb-util), x11-toolkit/gtk20,
 multimedia/kaffeine (which is a KDE software and depends on libxcb),
 and x11-wm/awesome (which depends on libxcb and xcb-util).
 All of them succeeded without xcb-proto.
