Did you check that some compilation fails because of this?
If not, how did you find the information that the location is changed?

On Ubuntu 10.04, the libs are in

	/usr/lib/i386-linux-gnu/

The same seems to be true for the current Ubuntu 10.10 packages:

	http://packages.ubuntu.com/oneiric/i386/libxrender1/filelist

Do you have a link where the change of location is explained?

These paths can be found runtime via pkg-config,

	pkg-config --cflags-only-I xproto
	pkg-config --libs-only-L xproto

However, the convention typically is "#include <X11/Xlib.h>"
so having only "/usr/include" in the path should be OK. But maybe
just hardcoding more paths would be enough.

There's a lot of stuff in `system_info`...
