Then don't use more than 512MB, I certainly wouldn't use less for the packages you mention. > So what do your think?

Packages that need a particularly large amount of space usually check its availability at the start of the emerge process. There's nothing to stop you using tmpfs for the default PORTAGE_TMPDIR and resetting it to somewhere on your drive for particularly large packages, using package.env Put "cat/pkg tmpondisk.conf" in /etc/portage/package.env and "PORTAGE_TMPDIR=/a/disk/dir" in /etc/portage/env/tmpondisk.conf -- Neil Bothwick Engineers do it with less resistance.
