Are you proposing to remove ffmpeg option like r490300? Another example is print/freetype2 which passes --without-harfbuzz. If you build manually then recursive dependencies are not an issue e.g., 1. Build multimedia/ffmpeg with VAPOURSYNTH option disabled 2. Build multimedia/vapoursynth with ASS option enabled 3. Build multimedia/ffmpeg with VAPOURSYNTH option enabled Recursive dependencies are a long-standing unsolved framework issue that requires ports being able to specifiy options in dependencies e.g., Index: multimedia/vapoursynth/Makefile =================================================================== --- multimedia/vapoursynth/Makefile (revision 534294) +++ multimedia/vapoursynth/Makefile (working copy) @@ -74,8 +74,9 @@ VSSCRIPT_CONFIGURE_ENABLE= vsscript # PLUGINS group ASS_DESC= Subtitles rendering via libass -ASS_LIB_DEPENDS= libavcodec.so:multimedia/ffmpeg \ - libass.so:multimedia/libass +ASS_BUILD_DEPENDS= ffmpeg>0:multimedia/ffmpeg[VAPOURSYNTH=off] +ASS_RUN_DEPENDS= ffmpeg>0:multimedia/ffmpeg +ASS_LIB_DEPENDS= libass.so:multimedia/libass ASS_USES= iconv ASS_CONFIGURE_ENABLE= subtext or Index: multimedia/vapoursynth/Makefile =================================================================== --- multimedia/vapoursynth/Makefile (revision 534294) +++ multimedia/vapoursynth/Makefile (working copy) @@ -74,7 +74,7 @@ VSSCRIPT_CONFIGURE_ENABLE= vsscript # PLUGINS group ASS_DESC= Subtitles rendering via libass -ASS_LIB_DEPENDS= libavcodec.so:multimedia/ffmpeg \ +ASS_LIB_DEPENDS= libavcodec.so:multimedia/ffmpeg[!VAPOURSYNTH=build] \ libass.so:multimedia/libass ASS_USES= iconv ASS_CONFIGURE_ENABLE= subtexthelp
