FF3 was unmasked in package.keywords, but it’s stable now, so no longer needed. The unmasked gtk+ was starting to cause problems.
Remove from package.keywords:
#www-client/mozilla-firefox
#dev-libs/nspr
#dev-libs/nss
#net-libs/xulrunner
#www-client/epiphany
#dev-util/intltool
#gnome-extra/yelp
#dev-libs/glib
#x11-libs/gtk+
#media-libs/libcanberra
#gnome-base/gail
Add:
# for rubyripper
dev-ruby/rcairo
# for boost
app-admin/eselect-boost
And…
emerge --unmerge texlive
Also note that xorg server 1.5 is stable now! Whoop!
