No, it isn't!  The first occurrence of FT_Int is in line 7960:

  extern FT_Int
  FT_Trace_Get_Count( void );

but FT_Int is defined in line 10470:

  typedef signed int  FT_Int;


I'm now sure that there's a severe mangling of FreeType 1 and
FreeType 2 header files: If you do a `grep /usr/local/', you see this:

  # 1 "/usr/local/include/ft2build.h"
  # 1 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftheader.h"
  # 1 "/usr/local/freetype2/freetype-2.3.5/include/freetype/internal/internal.h"
  # 723 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftheader.h"
  # 57 "/usr/local/include/ft2build.h"
  # 1 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftoption.h"
  # 1 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 1 "/usr/local/include/standards.h"
  # 56 "/usr/local/include/standards.h"
  # 37 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 67 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 82 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 106 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 124 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 162 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 175 "/usr/local/freetype2/freetype-2.3.5/include/freetype/config/ftstdlib.h"
  # 1 "/usr/local/freetype2/freetype-2.3.5/include/freetype/internal/ftdebug.h"
  # 1 "/usr/local/include/freetype/freetype.h"
  # 1 "/usr/local/include/freetype/fterrid.h"
  # 34 "/usr/local/include/freetype/freetype.h"
  # 1 "/usr/local/include/freetype/ftnameid.h"
  # 35 "/usr/local/include/freetype/freetype.h"


The problematic line is after inclusion of `ftdebug.h': This header
file loads FT_FREETYPE_H, which expands to <freetype/freetype.h>, and
since you have `/usr/local/include' before
`/usr/local/freetype2/freetype-2.3.5/include', the wrong `freetype.h'
(from FreeType 1) gets loaded.

With other words, `-I/usr/local/include' must come after
`-I/usr/local/freetype2/freetype-2.3.5/include'.
