>Description:
tmux-1.5 from the latest pkgsrc seems not to run. Upon invoking, the shell 
returns immediately. Upon checking the return code, it is 1:

[xcitor> tmux
[xcitor> echo $?
1
[xcitor>
>How-To-Repeat:
Run tmux from a shell prompt. I have tried moving my .tmux.conf out of they 
way, and the behavior is the same.
