Okay, it seems you're missing the headers. Couple of things you might
try:

	+ Does Suse have a ruby-devel package ? If so, get that.

	+ Beg/borrow/steal the appropriate headers, and copy them to
	  that directory (maybe not a good idea).

	+ Alternatively, grab a copy of the source and build it
	  yourself. You could upgrade to 1.8.4 at the same time ;)
