Comment (by ryandesign@…):

 The freetype CHANGES file explains:

 {{{
 CHANGES BETWEEN 2.5 and 2.5.1

 ...

   II. IMPORTANT CHANGES

 ...

     - The header  file layout  has been changed.   After installation,
       all files are now located in `<prefix>/include/freetype2'.

       Applications  that  use   (a)  `freetype-config'  or  FreeType's
       `pkg-config' file to get the include directory for the compiler,
       and (b) the documented way for header inclusion like

         #include <ft2build.h>
         #include FT_FREETYPE_H
         ...

       don't need any change to the source code.
