我试过 1) 出现 nodejs
!!! ARCH is not set... Are you missing the '/etc/make.profile' symlink?
!!! Is the symlink correct? Is your portage tree complete?
2) 从 Linux Binaries nodejs 下载（尝试 32 位和 64 位）
bin # ./node
Exception en point flottant
3）从代码源：
Waf: Leaving directory `/node-v0.4.10/build'

我还能尝试什么？有没有准备好为 gentoo 64 位预编译？
问候
