awesome dependency cairo-xcb

[jamesabernard@…]

Awesome WM not compiling because of missing dependency of cairo-xcb. As xcb is now supported in cairo, is this dependency now defective? I can't find way round, don't know how to change comile flags or whatever. Help would be appreciated.

I have figured this out:
install cairo +x11_xcb and then awesome will compile
Shouldn't cairo +x11_xcb be a dependency? as the standard cairo doesn't have xcb support?
