Building tmux 1.8 on CentOS 5.9Edit
Having done this for tmux 1.7 in "Building tmux 1.7 on CentOS 5.8", all that was required was:
$ wget http://downloads.sourceforge.net/tmux/tmux-1.8.tar.gz
$ tar xzf tmux-1.8.tar.gz
$ cd tmux-1.8
$ PKG_CONFIG_PATH=$HOME/lib/pkgconfig CFLAGS="-I$HOME/include -I$HOME/include/ncurses" LDFLAGS="-L$HOME/lib" ./configure --enable-static --prefix=$HOME
$ make && make install
