It turns out that pixman.h is only in directory pixman-1/ ... provided 
by recipe Pixman which is currently part of meta Xorg (I have Xorg 
7.3-r7 installed).  (Cairo >= 1.5 (development version) depends on 
Pixman but only optionally on Xorg, so I think Pixman should sometime be 
factored out as a dependency rather than a part of Xorg.)  Anyway, here, 
somehow the include isn't working properly, even though it's from an 
xorg header and Xorg compiled properly!  Any idea what's wrong?
