Cross Compiling to Ubuntu or Debian System from Gentoo client

Came across this error while trying to set up my 2 ubuntu boxen to compile with distcc for my gentoo laptop and workstation.

(dcc_execvp) ERROR: failed to exec i686-pc-linux-gnu-gcc: No such file or directory

Solution:

add

CC='gcc'
CXX='c++'

to your make.conf file.

I also had to

apt-get install distcc build-essential
