For those in the same boat, here's some configure.in code to test for the
freetype version:

    AC_MSG_CHECKING([for version of FreeType])
    FREETYPE_INCLUDE=`freetype-config --cflags | cut -c3-`
    FREETYPE_MAJOR=`grep '^#define FREETYPE_MAJOR' 
$FREETYPE_INCLUDE/freetype/freetype.h | cut -d' ' -f3`
    FREETYPE_MINOR=`grep '^#define FREETYPE_MINOR' 
$FREETYPE_INCLUDE/freetype/freetype.h | cut -d' ' -f3`
    FREETYPE_PATCH=`grep '^#define FREETYPE_PATCH' 
$FREETYPE_INCLUDE/freetype/freetype.h | cut -d' ' -f3`
    FREETYPE_VERSION=`echo | awk "BEGIN { printf \"%d\", ($FREETYPE_MAJOR * 
1000 + $FREETYPE_MINOR) * 1000 + $FREETYPE_PATCH;}"`
    AC_MSG_RESULT([$FREETYPE_MAJOR.$FREETYPE_MINOR.$FREETYPE_PATCH])
    if test "$FREETYPE_VERSION" -ge 2000009; then
