No way. This is Gentoo (The best distro in the world)'s automated qemu-cvs 
ebuild. It works this way: I have to type emerge qemu-cvs and it updates 
its private copy from cvs and then copies this private copy to 
/var/tmp/portage/qemu-cvs-1.5/work and builds it there. (It removes any 
files from this dir before copying of course.) So the source is always 
clean (as in the CVS).

But the good news is that Fabrice updated CVS and current version builds 
ok for me.

BTW. I got this ebuild from this list and modified it some time ago to 
work with newer versions (there were some changes to directory structure 
of qemu installation) and I synchronized this ebuild with official qemu 
release ebuilds. When using this ebuild you should put softmmu into USE 
and you should probably NOT put qemu-fast as it is known not to work with 
recent glibcs / binutils / gccs.

I do not remember if I posted the modified ebuild, so here it is:

# qemu-cvs-1.3 and previous by Gabriel Ebner <address@hidden>.

#       * some minor fixes
#
# qemu-cvs-1.5 Grzegorz Kulewski <address@hidden>
#       * fixed access violation with current CVS in make install
#         (added datadir variable)
#       * added qemu-fast use flag (do NOT use it yet!)

Does anybody have better or more correct version?
