Kernel compile returns error regarding SCSI emulation.

["K. G. Suarez" <kgs245@xxxxxxxxxxxxx>]

I installed DragonFly this afternoon and had spent most of the evening 
waiting for the updating to finish. While running running "make 
buildkernel KERNCONF=KOCHAVIT" I received an error. I don't remember 
what it was (I wish I would have saved before going off to fix it.), but 
I do remember what fixed it; I reedited my kernel config file and 
commented out a line that enables SCSI emulation. I was able to finish 
the build, install, and reboot. Everything seems to be working fine so 
far. Does anyone know what could have caused the build error? What will 
having disabled SCSI emulation do to my system's performance?
