This just means that non-supersymmetric SU(5) theories are ruled out,
right?  My understanding was that there were still a number of viable
SO(10) and E(6) models.  

(For non-specialists, by the way, the main difference between SU(5)
and the more complicated GUTs is that SU(5) doesn't predice any
interesting physics between the electroweak scale (100 GeV or so) and
the GUT scale (10^15 GeV or so), but the other GUTs have intermediate
scales.)

Matthew Austern              I dreamt I was being followed by a roving band 
(510) 644-2618               of young Republicans, all wearing the same suit,
matt@physics.berkeley.edu    taunting me and shouting, "Politically correct
austern@theorm.lbl.gov       multiculturist scum!"... They were going to make
austern@lbl.bitnet	     me kiss Jesse Helms's picture when I woke up.
