xcb and in fact all the "new" xlib packages have their PKG_CONFIG_PATH as
/opt/csw/X11/lib/pkgconfig

when doing anything that requires CSWx* packages you need to use something
along the lines of: EXTRA_PKG_CONFIG_DIRS = $(prefix)/X11/lib

I think pkg-config is walking down the dependency trail.  cairo is required for
gtk, but xcb is required for cairo. it couldn't find xcb so it quit instead of
spending an hour compiling just to die a horrible death when trying to link to
the missing xcb libraries.
