Kernel compile returns error regarding SCSI emulation. Details included.

Hello everyone.

I installed DragonFly yesterday 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:

/*****************************START*******************************/

/****************************END*********************************/

When 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. This is the line, under "# ATA and ATAPI devices":

/*****************************START*******************************/

device      atapicam      # Emulate ATAPI devices as SCSI via CAM

/*******************************END******************************/

Everything seems to be working fine after removing that line. Does 
anyone know what could have caused the build error?
