This is a trick that works occasionally: (Don't ask me why. I try it only out of desperation when I don't know what else to try) #quickpkg =webkit-gtk-2.4.7-r200 #quickpkg =webkit-gtk-2.4.7 #emerge -C =webkit-gtk-2.4.7-r200 =webkit-gtk-2.4.7 Removing webkit will break any other packages that depend on it, but now that you've saved your existing webkit packages with quickpkg, you can reinstall them using emerge -K if my trick doesn't work for you. Here's another desperation move I make sometimes when I'm out of ideas: #cd /usr/lib #ls -lSr (this sorts your libraries with the oldest ones at the end) #qfile ./my-geriatric-lib.so.<whatever> Then start emerging the oldest packages first, but do it one at a time instead of using emerge -e to do everything with one giant step.
