InsightToolKit did not build

	I am not going to ask you to build on the 466 MHz, that might take  
you to until the next decade.
	Sounds like Apple needs to do a little work on the intel scheduler.   
Even running with both cpu's at or near 100% (which means a faster bus  
would not buy me very much since I am getting 100% cpu usage at a 13:1  
cpu:bus ratio), I only notice a slowdown when trying to launch new  
applications.  Once up and running, there is not much difference in  
response time.  PPC G4's range between 1.25 to 1.5 the throughput rate  
of equivalent Intel cpu's due to an average of 1.8 (maximum of 3)  
completed instructions per clock cycle.  You have a 2.75:1 cpu:bus  
ratio, so I wonder what the hold up is.
	I think I might need a faster bus if I could get a hold of dual core  
e600's (the inside of my PPC 7448) which Freescale does not make.   
Right now they only make a single core e600 µ-Processor and a dual  
core e600 µ-Controller.
