Created attachment 221589 [details] patch for additional format
Comment on attachment 221587 [details] new ebuild Your ebuild leaves in a lot of deprecated stuff, including hard-coded libs/cflags for mysql and postgresql and the blocker between the two related USE flags. 0.68.5 doesn't appear to need any of all that. I am working on a new ebuild that is a lot cleaner and friendlier than what we had in the tree so far.
I have put 0.68.5 in the tree. Thanks for reporting and please test it thoroughly. File a new bug report if you find any issues.
