Hi Graham.
Here is Götz Wilhelm Renger from Berlin.

How can I show you my 'system settings for application style and for window
decorations'? 

I've changed my /etc/portage/make.conf to 
COMMON_FLAGS="-march=core2 -Og -ggdb"

With this, is it possible to produce a better failure log. If so, what I've to
do to deliver a better failure log then the following:
