It's a "Linuxism". :-) Because it's a Linux program, you have
to make sure that linprocfs is loaded. Usually it's mounted
in /usr/compat/linux/proc, but the install script seems to
expect cpuinfo in /proc (which is FreeBSD's proc), so it
cannot be found.

You can, however, mount the Linux procfs in /proc, everything
should be working then. To get this state automatically after
startup, add

	linproc	/proc	linprocfs	rw	0	0

to your /etc/fstab.

The call "cat /proc/cpuinfo" will work. Example:

	% cat /usr/compat/linux/proc/cpuinfo 
	processor       : 0
	vendor_id       : GenuineIntel
	cpu family      : 6
	model           : 16
	model name      : Intel(R) Celeron(R) CPU 2.00GHz
	stepping        : 9
	flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr
	                  pge mca cmov pat pse36 b19 b21 mmxext mmx fxsr
	                  xmm b26 b27 b28 b29 3dnow
	cpu MHz         : 2018.20
	bogomips        : 2018.20
