I am trying to compile Cairo.

What do I need to do so Intrinsic.h is found by the compiler?
Usually the location of include files is set at configure time. For R, I use
../R-devel-src/configure --with-x --x-includes=/opt/X11/include --x-libraries=/opt/X11/lib
It's not clear to me whether Cairo is the R package or an external library, but if it's the R package, you might try
install.packages("Cairo", type = "source", configure.args = "--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib")
