I believe that Qt expects to find: "libXft.so.2" in: /usr/X11R6/lib/"

Try making a link.

If that doesn't work, rename the link: "libXft.so" and run: "ldconfig".

You are missing:
	
	XftFreetype.h

It should be in: "/usr/X11R6/include/X11/Xft/" find it and make a link to there.

Be sure that you have the correct version of Xft.h -- v. 1.3, I think, and it needs to be in: 
"/usr/X11R6/include/X11/Xft/".

Also, where is FreeType2 installed?
