Check gittup http://gittup.org/gittup/

This is a Gentoo-like distributive that uses Tup tool. The distro
includes kernel/gcc/glib/zlib/binutils/ncurses/openssh/openssl/mplayer/...
and some other projects.

And it is *very* fast for incremental builds. Just a short snippet
from the gittup page:

[marf@captainfalcon gittup]$ vi nethack/src/spell.c
[marf@captainfalcon gittup]$ vi busybox/coreutils/ls.c
[marf@captainfalcon gittup]$ time tup upd -j2
Executing Commands
[ 0/9 ] busybox/coreutils/CC ls.c
[ 1/9 ] nethack/CC src/spell.c
[ 2/9 ] busybox/coreutils/LD built-in.o
[ 3/9 ] busybox/LD busybox
[ 4/9 ] nethack/LD nethack
[ 5/9 ] initrd/bin/CP busybox
[ 6/9 ] initrd/bin/CP nethack
[ 7/9 ] initrd/MKINITRD
[ 8/9 ] initrd/GZIP initrd
[ 9/9 ]

real 0m1.571s
user 0m1.888s
sys 0m0.269s

Rebuilding whole system in 1.5 sec, isn't it cool?
