config/config.guess: unable to guess system type This script, last modified 2012-02-10, has failed to recognize the operating system you are using. It is advised that you download the most up to date version of the config scripts from http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD and http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD The bug is fixed by simply download the new config.guess and replacing the old one with the new one.

config.{sub,guess} do not get patched by ebuilds. if glew isn't running econf (which is how portage automatically updates these files), then it can inherit the gnuconfig eclass and use `gnuconfig_update` in src_prepare.
i've fixed it by reworking how we handle SYSTEM: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=234f6d457396c138cf76dcc8f3973ece14845410
