Hmm, PATH on the client machine has /usr/lib/distcc/bin at first, aswell 
as the server /etc/profile, however, distcc echoes
something along the lines with "distcc 2.18.3 trace: compiler name is 
x86_64-pc-linux-gnu-gcc, setting PATH="/usr/local/sbin:/usr....". That 
must be the problem. Might i ask where I'm supposed to define the PATH?

Thanks.
Daniel.
