[gentoo-user] Permanent workaround for x11-libs/libxcb build problem

[Walter Dnes]

  Some machines (e.g. my laptop) experience problems when building the
package x11-libs/libxcb

  Every so often libxcb gets (re)built and this error pops up.  It's
always vaguely familiar, so I dig through my gentoo list email, and
figure out that libxcb wants 'LC_ALL="C"' and set it for that one time.
I got tired of re-doing this all the time.  This problem is a textbook
example for package.env.  Two one-line files solve the error permanently. 
Make sure that you've created directories "/etc/portage/package.env/"
and "/etc/portage/env/".  Here are the two one-line files.

[thimk2][root][~] cat /etc/portage/env/libxcb.conf 
LC_ALL="C"

[thimk2][root][~] cat /etc/portage/package.env/package.env 
x11-libs/libxcb libxcb.conf

  If you're already using package.env, add the line...
x11-libs/libxcb libxcb.conf
...to your existing package.env file.
