distcc

[Couannette]

in environment:
export DISTCC_HOSTS="localhost gimli celebhost"
export DISTCC_VERBOSE=1
export DISTCC_LOG=/var/log/distcc.log

in lin:
MAKES=4
=> lin alias make to make -j4

/usr/lib/distcc/bin is first in $PATH
lin inserts /var/lib/lunar/compilers in front
I wipped out all files in this last directory (no more lunar wrappers)

Thus when I : sh -x /sbin/lin -c a52dec
I expect build will call:
make -j4
/usr/lib/distcc/bin/gcc

But noway ! I run tail -f /var/log/distcc.log on all hosts and there is 
nothing !!!
(I've the same setup for DISTCC on all hosts).

BUT when I cd in /usr/src/a52dec and do make clean; make -j4, I see jobs 
spawned on my two hosts (localhost & gimli) powered on.

WHO COULD EXPLAINS THAT TO ME ?
