oops, I take a deep look.  It turn out that
this package set the flags (for SDL, etc.) as 'CFLAGS',
but it only use 'CXXFLAGS' (only have freetype) when compile cpp files.
I think we can patch the Makefile after 'configure' phase, by:

  (substitute* "Makefile"
    (("CXXFLAGS =") "CXXFLAGS = ${CFLAGS)"))

And better, ask upstream for a real fix :-)
