Any way to add USES clause depending on two options without including bsd.port.options.mk?

| Depends on the port but here're some ideas:
| 
| - Move to a common option via _IMPLIES (e.g. GPL3 in multimedia/ffmpeg)
| 
| - Nest or create custom option helpers e.g.,
| 
|     OPTIONS_DEFINE=	GUI NLS
|     GUI_VARS=	NLS_USES=gettext
|     
|     # pkg-plist
|     %%GUI%%%%NLS%%share/locale/foo/LC_MESSAGES/bar.mo

This is a bad idea, it depends on an implementation detail.

Please don't do it.
