I don't know if this is a local issue, a header issue, or the package  
needs to be changed:

In file included from machine/cpu.h:57,
		 from machine/param.h:48,
		 from /usr/src/sys/sys/param.h:145,
		 from aperture.c:49:
/usr/src/sys/sys/device.h:83:26 prop/proplib.h: No such file or  
directory


I tried to run make includes but there seems to be an extra / getting  
picked up in the makefile somewhere, USETOOLS=no goes a little  
further but then dies when it hits crt stuff.

includes ===> sys/arch
