the latest build of ion3 from mabi's overlay fails with the new ion. If you've upgraded lua first, then ion3 will fail to compile. Otherwise, ion will fail to start with a seemingly random error mode. Reproducible: Always Steps to Reproduce: 1. install newest lua 2. install/run ion3 Actual Results: ion3 installs/runst Expected Results: fails to do either there is apparently a rather experimental ion3+ darcs repo that can theoretically be used.
Simple solution: USE="deprecated" with lua. I'll make the ion ebuild force that flag.
