for those of you who complain about the compiling taking too long, just emerge the binary of the package or generate a binary using the emerge --buildpkg option (i.e. "emerge --buildpkg mozilla") and you can just copy the tbz2 from
/usr/portage/packages/All/ to whatever system you need to install gentoo on and emerge the tbz2. Of course, you'll want to make sure the optimizations don't conflict across the different systems, but you can modify the /etc/make.conf file and downgrade some of the optimizations to be more compatible before building. of course, this doesn't help first time compiles, but guess what? Gentoo is a source-based distribution. it's not a binary package distribution. so stop whining about how the compiling takes too long; get a faster computer or get debian. just stop complaining.
