In addition to my trunk Inkscape builds, i have also started building trunk builds of the GIMP “Goat Invasion”. The “goat invasion” builds of the GIMP are basically what GIMP 2.10 will be with all the GEGL library goodness (this blog post is a good outline of some of the improvements GEGL provides the GIMP).
Note that currently only the 64bit version of these builds on Fedora 19 is available. If there is enough demand i may build for other targets.
To set this up on your Fedora machine, first download the .repo file:
sudo curl -o /etc/yum.repos.d/fedora-gimp-goat-invasion.repo http://repos.fedorapeople.org/repos/ryanlerch/gimp-goat-invasion/fedora-gimp-goat-invasion.repo
Then tell yum to update inkscape:
sudo yum update gimp
