 	Yes ,  AS200 4/100 ,  Painful I don't need ,  But it's better than 
attempting to find the right combinations of shareable libraries & compiler 
flags are required to cleanly compile most of the gnu stuff .

 	And yes I have been trying mostly unsuccessfully to compile some of the 
tools/utilities I have grown accustomed to on the linux platforms .  Tho I am 
not a fan of rpm .  So ... Off I go again .
