XFree86 4.6.99.24 (21 May 2007)
 150. Fix build with an external freetype2 library (both newer and older than
      the version we provide under xc/extras/).  However, still build
      libXfont's FreeType backend module with the freetype2 version we provide
      because it is the only version known to be modified to correctly build
      the module.  Problem reported in Bugzilla #1683 (Jie Luo, Marc La France).
