30 Why not just NFS-export your $PORTDIR to a chroot on your host machine, and
31 build everything there? --sync takes quite a while, but that would easily be
32 recouped in compilation. That's what I do with a little Atom N270 box here.

34 $ genlop -t gcc -f /mnt/atom/var/log/emerge.log | grep minutes
35 [...]
36 merge time: 13 minutes and 11 seconds.
37 merge time: 13 minutes and 35 seconds.
38 merge time: 12 minutes and 51 seconds.
39 merge time: 14 minutes and 16 seconds.
40 merge time: 14 minutes.
41 merge time: 26 minutes and 49 seconds.
42 merge time: 28 minutes and 41 seconds.
