On my system, I have 
   /usr/include/ft2build.h and
   /usr/include/freetype2/freetype/freetype.h. 
Both files are part of the Redhat package freetype-devel-2.1.3-6.

The OP seems to be missing /usr/include/ft2build.h for whatever reason,

To compile code that uses freetype 2 I use -I/usr/include/freetype2 (or
whatever is returned by the shell command `freetype-config --cflags`), 
and in the source files, 
   #include <ft2build.h>
   #include FT_FREETYPE_H.
where FT_FREETYPE_H is a macro defined (indirectly) in <ft2build.h>.

I believe this is the canonical way of compiling with Freetype 2.

I have no idea what should be the advantage of all this convolution.
The use of these macros do not remove the need to add an element to the
include path. Of course, each level of indirection added is an added
opportunity for the administrators to relocate file trees, but that
possibility already exists in freetype-config.

I guess the advantage is that a future freetype3 needs not redefine all
the headers, and so the macros in ft3build.h can point at some ft2 files
and some ft3 files. Hooray.

The file ft2build.h must also be in the include path.
