The above solved the pixman problem but it still seems that Cairo is
getting the wrong include path for DirectFB.  Looking at the directfb.pc
file, I see this line:
	Cflags: -D_REENTRANT -I/include/directfb
shouldn't that line be:
	Cflags: -D_REENTRANT -I/usr/include/directfb

Can you send me your ..package/directfb/directfb.mk 

Thanks
