tmux's configure script detects the presence of utempter if present. If sys-libs/libutempter is later depcleaned, tmux fails to exec. Reproducible: Always Steps to Reproduce: 1. emerge sys-libs/libutempter 2. emerge app-misc/tmux 3. unmerge sys-libs/libutempter 4. exec tmux Actual Results: ld.so fails to locate libutempter.so.0. Expected Results: tmux executes normally. There doesn't seem to be a configure flag to control this behaviour.
Indeed. I should have set up a USE flag instead of a blocker. Not sure there's one for this particular library (utempter).

Thanks for fixing this up Jason. I forgot about this bug and didn't get round to looking at it again.
