ports/144760: sysutils/tmux: shell not working in tmux any more

[Barak Michener]

I tried your patch -- it didn't work. However, David's message helps:

Looking inside the configure script for tmux in the source package, 
there's a line for Darwin-based systems:

#define HAVE_BROKEN_KQUEUE

copying that line to the FreeBSD section and compiling makes tmux-1.2 
work great :)

This is my first email to the ports list, so I don't have much 
Makefile-foo. The patch you gave me didn't work, but I think you're on 
the right track...
