Subject: Rebuild all gems? (Or all which have native extensions?)

Ruby 1.9.0-4 instantly broke Hpricot. Reinstalling from the gem fixed it.

Now, this shouldn't happen, but I'm compiling the development version of Ruby 
from source, so I should be expecting issues like this.

But for that particular problem, is there a way to automagically rebuild all 
gems? Or at least those with native extensions -- I'd guess those would be 
the first to break.
