I am using 2 Gentoo-Machines with distcc and ccache. distcc works, I can see
that with gkrellm, top and in my syslog.
But distccmon-text and distccmon-gnome do not work: they just show blank lines.

I invoke the command on the client-machine (I tried the server-machine too) with
DISTCC_DIR=/var/tmp/portage/.distcc distccmon-gnome

and it doesn't work. I have read that there might be a permissionproblem:
It has to be executed as portage-user or as the same user that compiles/emerges
on the server.

So I tried
DISTCC_DIR=/var/tmp/portage/.distcc sudo -u portage distccmon-gnome

But that doesn't work too. I am emerging and compiling as root and the command
doesn't work when I'm root.

I have read that I should watch the DISTCC_DIR while I execute
distccmon-text/gnome but in that directory doesn't happen anything.

I checked the permissions from that directory but that seems to be ok:
drwxrwsr-x     4 portage portage    96 13. Jul 14:00 .distcc

/var/tmp/portage/.distcc:

Then I have read that I should try an strace but I cannot see something there:

I have checked every google-page, the gentoo-distcc-manual and some forums but
nothing helps...
