What freebsd version are you using?
Also, can you paste the output of "sysctl kern.smp.maxcpus" and "sysctl 
kern.cp_times" commands?

Wondering whether we can freely use kern.cp_time as replacement. Apparently it seems so.
On the other hand I've just tried to compile psutil on freebsd 7 and I get 
different compiling errors.
It seems at some point we broke support for it. :(

Ok, we cannot use kern.cp_time.
After some research it seems there's no easy/immediate way to gather per-cpu 
stats on free bsd versions < 8.0.
I'm even inclined to think there might be no way at all because:

- "top -P", which shows this info, doesn't work on free bsd 7
- "htop", which provides this info without any option, requires some 
preliminary setup to be installed in the first place: 
http://daemon80.blogspot.com/2007/09/htop-in-freebsd.html Other than that I'm 
realizing we have some other incompatibilities which are annoying to fix: 
Process's get_open_files() and getcwd() don't work because kinfo_file structure 
doesn't exists.

At this point I think we have 2 possibilities: drop support for freebsd 7 or 
drop support for those functionnalities which are not working.
Since freebsd 7 appeared only 3 years ago: http://www.freebsd.org/releases/ 
...I think it makes more sense to go with the second option.

Fixed in r1206 , which is a commit I'm really ashamed of. =)
