It provides extra isolation features. If you are sure you don't need
that, ignore it.

emerge-ing seems work, can't I just ignore the message (I don't need
that namespace elsewhere in the system) ?

If you use gentoo-sources, the option GENTOO_LINUX_PORTAGE ("Gentoo Linux" ->
"Gentoo Linux Support" -> "Select options required by Portage features") will
automatically select them.

Your kernel is probably missing a features used by the new versions of portage. I'd say something like CONFIG_PID_NS from the General Setup/Namespaces support section. If you built your own kernel, try to activate this feature. -- Hervé Guillemet
