Hi ruby devs,
in the latest release you dropped the possibility to tell ruby to build
without x... at least as i can see.
So my question is - as this might be true for other extensions:
How to disable extensions?
I've seen those Setup files in ext/ but they only affect static builds or
something like that if i'm not wrong.
So what's the right knob to fiddle with?

Kind regards
Simon

P.S.: And thanks for your work, which lets us build soooo smooth and
elegant applications.
