Description Aniruddha Shankar 2022-04-14 11:27:09 UTC

I wanted to use byobu without the tmux backend so I installed byobu after adding screen to the USE flags. However, byobu does not run. byobu-screen does run properly. 

Reproducible: Always

Steps to Reproduce:
1. Install app-misc/byobu-5.133 with USE="screen" 
2. Attempt to run byobu

Actual Results:  
/usr/bin/byobu: line 242: exec: tmux: not found


Expected Results:  
byobu should run using screen as the backend.

zakalwe ~ # emerge -vp byobu

These are the packages that would be merged, in order:

Calculating dependencies... done!

zakalwe ~ # cat /etc/byobu/backend
# BYOBU_BACKEND can currently be "screen" or "tmux"
# Override this on a per-user basis by editing "$BYOBU_CONFIG_DIR/backend"
# or by launching either "byobu-screen" or "byobu-tmux" instead of "byobu".
BYOBU_BACKEND="screen"

After installing twm and xterm, this problem does not occur - seems to be limited to console installations only, perhaps?
