Because current pkgsrc's bmake have a bug to read _ALL_ mk files in mksyspath,
so except ${PREFIX}/share/mk has been removed from mksyspath.
If set makesyspath=${PREFIX}/share/mk:/usr/share/mk and those two directores
have same name files, unexpected trouble may be occured.

Why not simply add following line to depend on mk-files?
DEPENDS+=	mk-files-[0-9]*:../devel/mk-files
