That's the point. The metaports should be installed as well (reasons given 
in my original mail).

I know this.

The proper way to make a metaport is to:
1. use only RUN_DEPENDS
2. set NO_BUILD
3. do *NOT* set NO_INSTALL
4. provide empty do-install target

There are several metaports that get it right, like for example x11/gnome2:
