I am working on an update of gnash.

I .include "../../audio/SDL_mixer/buildlink3.mk"
but later my build fails due to missing -laa.

$ objdump -x /usr/pkg/lib/libSDL_mixer.so | grep NEED.*libaa
  NEEDED      libaa.so.1

I have: smpeg-0.4.4nb12, SDL_mixer-1.2.6nb4, and SDL-1.2.9nb2.

I don't want to include buildlink for aalib directly. The SDL 
buildlink3.mk has:


.if !empty(PKG_BUILD_OPTIONS.SDL:Maalib)
.include "../../graphics/aalib/buildlink3.mk"
.endif


But I don't see PKG_BUILD_OPTIONS.SDL defined when I configure my gnash 
package.

I looked at ../../mk/pkg-build-options.mk and then manually ran:

$ pkg_info -Q PKG_OPTIONS SDL   
$ 

Nothing.

I don't know when this was added.

Should packages have their revision bumped and the 
BUILDLINK_API_DEPENDS.${foo} bumped when a build method is changed like 
this?
