>Description:
cairo link fails with unresolved symbols from X11 library if xrender pkgconfig 
files are installed (particularly when USE_BUILTIN.xrender=yes). Cairo's 
configure.in includes -lX11 to XRENDER_LIBS if the pkgconfig file is not 
present - but when the pkgconfig file is present, -lX11 is not included in any 
LIBS, resulting in link failure if xrender's pkgconfig Libs does not happen to 
include -lX11.
>How-To-Repeat:

>Fix:
Some m4-syntax magic in cairo's configure.in to say "if use_xlib==yes, include 
-lX11 in libs, regardless of what xrender brought with it".
