awesome needs two deps fixes: libpng and cairo+x11_xcb

[jeff.pitman@…]

I recently did a full upgrade and found that awesome didn't recompile when libpng was upgraded. In addition, when I uninstalled it and recompiled/installed awesome, I found that it depended on cairo+x11_xcb in the build but not in the port dependency. Therefore, it failed to compile.

$ port deps awesome
Full Name: awesome @3.4.4_0+x11_xcb
Build Dependencies:   cmake
Library Dependencies: lua, glib2, pango, cairo, xorg-libxcb, xorg-randrproto,
                      startup-notification, libxdg-basedir, ImageMagick, imlib2, libev

libpng should be in this list. And, the +x11_xcb should carry through.

Nothing recompiles automatically when its dependencies are upgraded. If a port needs to be rebuilt, its maintainer needs to increment its revision. The other part of this is a duplicate of #23483.
