I finally wrote a little program to check if kvm works on my FreeBSD 
box (see
attached file) outside the GNUstep context. I does not. Regardless 
what i tried,
I got the well-known error message 'kvmtest: cannot open 
/proc/30888/mem'
whenever kvm_getenvv was called. So I looked into the libkvm source 
code and
found the following line of code in the function kvm_uread:
sprintf(procfile, "/proc/%d/mem", kp->ki_pid)
kvm_uread is invoked indirectly by kvm_getenvv.

Grmpflz. Seems like kvm (at least the kvm_getenvv function) cannot 
work without
the proc filesystem. As mentioned earlier, I've disabled proc-fs on my 
box because
it has been suggested in the installation instructions.

The only way that seems to work for me is not to use libkvm on FreeBSD 
systems
without proc-fs support. I disabled kvm usage by hacking the configure 
script
and GNUstep works again. Can we add a flag like --without-kvm to 
configure in
gnustep-base?
