Hi, all.
I just find the cause -
1. Because of this line in Makefile
..include "../../graphics/freetype-lib/Makefile.common"

the patch dir be override by
PATCHDIR=               ${.CURDIR}/../../graphics/freetype-lib/patches

The patches under ttf2pk/ will never adopted.

2. Then I try to fix it by this line:
Index: Makefile

Then it printed out such errors -
