This is an auto-filed bug because app-benchmarks/wrk fails to compile. The issue was originally discovered on amd64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info. NOTE: If you need further logs, feel free to ask.

@ago: I am confused. It seems to fail of /bin/sh: luajit: command not found. But dev-lang/luajit is included in BDEPEND. I can't explain, why it's not on your system? Do you have an idea?
I can't reproduce anymore, let's close as WORKSFORME for now..
