Krunner Qalculate not working (Unit math, ie 1N*1m=1J)

Hi all. Im trying to get krunner to do unit math. I have opensuse 12.1 running either KDE 4.7 or 4.8 (tried both) and neither can do any engineering calculations. The Qalculate widgit works fine, and so does simple unit conversion. (Id like to throw in here that ubuntu has engineering math working, but no unit conversion. heh it knows what 500 ft * 30 N is, but not what 1 meter is in feet.)

Anyways, how can i get unit/engineering math in krunner working?

Thanks to anyone who can give some insight.
