echo "Append following line to your .zshrc or .bashrc or .bash_profile file"

Thanks for this helpful script. Just to add a bit more to make it a complete instruction

cmd to build tmux after installing dependencies locally

DIR="$HOME/local"
./configure --prefix=$HOME/local CPPFLAGS="-P" CFLAGS="-I$DIR/include" LDFLAGS="-L$DIR/lib"
make && make install

Then in order to use tmux, add path for static libs, e.g. libevent for tmux

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/loca/lib
tmux
