qtwebkit ships with its own (possibly with custom modifications) but due to several -L/usr/lib64 in the linker line, the system one is preferred over the bundled on linking. Reproducible: Always
Installed leveldb version was 1.9.0-r5

And what's wrong about using the system copy? Is this just a case of automagic dep?
Looks like the systemcopy is missing a some functions which the bundled one has. Probably the bundled is newer than the system copy or has a custom patch.
It seems Qt just prefer system leveldb to bundled one: https://qt.gitorious.org/qt/qtwebkit/commit/032ed118eeb3cb642720336a1ef67623bb97f9c4
This is still an issue with dev-qt/qtwebkit-5.4.1 from Portage.
As per comment #5, I've pushed a commit to the overlay for review to ensure that the system copy is used. https://gitweb.gentoo.org/proj/qt.git/commit/?id=fa9569964aba22b7849b2a91b38d4479e3a6293e

This is in-tree in 5.4.2.
I have a tip for those using LTO by default. Blacklisting QtWebKit5 from LTO is not enough as it will stop compiling on some undefined referenced to leveldb. Only hen both webkit and leveldb are stopped from using LTO will the compilation succeed. I am probably not supposed to write this in here, but I do not think the issue is big enough to write a full bug report; and I just want to save some time for anyone else who will search for the solution in future.
