I hit this one too. Any possible fixes?
Really, I think the answer is to update the package which is now at version 0.8.0
Created attachment 203337 [details] libinklevel-0.8.0.ebuild Here is a working ebuild for the newer version, found a patch from another bug, kink also compiles against it afterwards without any problems
0.8.0 is now in the tree.
Please reopen if it's not fixed in 0.8.0
