Hmm, I think that the Ruby headers should always be installed, in your
case it looks like they should be at:

	/usr/lib/ruby/1.8/i586-linux/

Could you verify the presence (or absence) of a bunch of .h files at
that location? If they're not there, then you should probably grab a new
Ruby install (is this one a package from your distro?).
