Hi,

I'm almost sure that I have the latest versions :)  This might also be
the problem :)

What is my distribution: Sorcerer
How did I update: augur easy

For your information:
Sorcerer is an sourcebased distribution like gentoo, it is just more
up to date, in regards to the different applications, and then it is a
lot easier to keep up to date, and to install (in my thoughts - but
one might have a different views upon these points).

But yes of course I can have a broken dependency on my box(es), if so
I'll be glad if anyone could say where it is broken, as qemu-snapshot
is the only application (which I know off) that I can not compile
successfully. But I'll of course keep updateing the box.

Now the versions:

glibc: 2.3.5
gcc:  3.4.4
linux: 2.6.11.11
binutils: 2.16
coreutils: 5.2.1

Did I miss any ? If so I'll gladly provide them

Best regards
