Installing gtk+-2.0.9 with Xfree86-4.2.99.1

[Byron Stanoszek <gandalf winds org>]

I'm having a little trouble compiling gtk+-2.0.9 with a Xfree86 cvs version
from a couple of months ago (4.2.99.1), and I get the following error during
configure:

Pango-1.0.5 compiled successfully, with part of its configure output reading
like:

Is there anything I can do or am I really supposed to have this
Xft/XftFreetype.h file? Maybe my particular release of XFree86 didn't install
this (I've recompiled XFree86 because installing the nVidia binary driver
screwed with my OpenGL libraries).

Thanks!
