The ebuild needs a simple s/ook/freckles/ It currently looks for: http://snapshot.opera.com/unix/ook_11.62-1273/opera-11.62-1274.x86_64.linux.tar.xz but the actual uri is: http://snapshot.opera.com/unix/freckles_11.62-1273/opera-11.62-1274.x86_64.linux.tar.xz That applies to 1273 as well.
My bad. Thanks for reporting. Fixed again.
