No problem. For what it's worth, setting up the 2.4.4-r1 ebuild in a local overlay (I used the instructions at http://www.funtoo.org/Git_local_overlay) seems to be working:
Follow the wiki instructions until it starts talking about rain-slick (the blue text). Create /usr/local/portage/net-libs/webkit-gtk/files/ Copy the original ebuild from /usr/portage/net-libs/webkit-gtk/webkit-gtk-2.4.4.ebuild to your local overlay at /usr/local/portage/net-libs/webkit-gtk/webkit-gtk-2.4.4-r1.ebuild Copy the original ebuild files in /usr/portage/net-libs/webkit-gtk/files to your local overlay at /usr/local/portage/net-libs/webkit-gtk/files Fix the SRC_URI var in the ebuild by adding an 'a' before the '.tar.xz':
SRC_URI="http://www.webkitgtk.org/releases/${MY_P}a.tar.xz"
Create the Manifest file
$ ebuild webkit-gtk-2.4.4-r1.ebuild digest
Now when you emerge webkit-gtk, it should pull from your local overlay with the fixed SRC_URI.
