Ralph, I never said anything about disagreeing with these cases. I'm
talking about purely optional features of packages which do not
have any bearing on runtime dependencies or cause breakage.

If a configure script offers switches for purely optional features, we
should, imo, 1) give the users use flags to control these features or
2)hard code the settings we want in our ebuilds.

What do you think?
