I just tried to use bcc with Lua (via the provided bcc-lua starter) to run the examples, and found that *nothing* works, and apparently has been broken for many years. Not a single example runs, and in fact not even the bcc-lua binary works correctly as it is underlinked (no libbcc.so reference), see the linked GH bug. Reproducible: Always Steps to Reproduce: 1. build bcc with USE=lua (enabled by default) 2. bcc-lua /usr/share/bcc/examples/lua/task_switch.lua 3. broken/crashes (see linked GH bug) Since this seems to be broken upstream since forever it's probably best to just disable Lua support in the ebuild.
