skill problems

[Anthony Philipp]

Hello,

When I did this:

$ skill ttype  

I got this back:

skill: proc size mismatch, recompile libkvm

Anyone know how to fix this? 
uname -a:
6.0-RELEASE FreeBSD 6.0-RELEASE #0: Mon Dec  5 11:19:03 CST 2005
pkg_info | grep skill
skill-4.1.1         SuperKILL, kill or renice processes by pid,
name, tty or ui

I've rebuilt world, and rebuilt the kernel with it, so I'm not sure
what else to do. I don't remember when this problem arose. 

Thanks in advance!

Anthony
