Sigh... Much hacking later... The damn things disappear!!! OK. I
re-emerged a lot... Update xorg-x11 as well because mythtv 0.19 needs qt
with opengl support... And my symlinks disappear... So I play with
eselect a bit & putting set -x in the relevant routins
in /usr/share/eselect/modules/opengl.eselect reveals that eselect is
busy trying to symlink opengl libs from /usr/lib32 which don't exist &
ignoring lib64...

Damn... Where is this stuff configured for eselect to do that?
