Very much so. I'd add one comment, in that you can do without LD_PRELOAD
if you setup /etc/ld.so.conf:
libc.so.12 machdep.fpu_present 1:/usr/pkg/lib/libkver.so.1,libc.so.12
I've tried using something other than machdep.*, but never got anything to work.
Either ld.so.conf(5) is wrong when it says you can use <sysctl_variable>, or
the source needs to be fixed to allow other sysctl entries.
Another comment would be why is libkver looking for a symlink outside of the /usr/pkg/
