安装tmux出错

Question

tar zxvf tmux-1.6.tar.gz
cd tmux-1.6
./configure
make
make install

进行到最后一步出错了，
非root用户报错如下

make[1]: Entering directory `/home/admin/Public/tmux-1.6'
test -z "/usr/local/bin" || /usr/bin/mkdir -p "/usr/local/bin"
  /usr/bin/install -c 'tmux' '/usr/local/bin/tmux'
/usr/bin/install: cannot remove ‘/usr/local/bin/tmux’: Permission denied
make[1]: *** [install-binPROGRAMS] Error 1
make[1]: Leaving directory `/home/admin/Public/tmux-1.6'
make: *** [install-am] Error 2

su报错如下：
`[root@localhost tmux-1.6]# make install
make[1]: Entering directory `/home/admin/Public/tmux-1.6'
test -z "/usr/local/bin" || /usr/bin/mkdir -p "/usr/local/bin"
/usr/bin/install -c 'tmux' '/usr/local/bin/tmux'
test -z "/usr/local/share/man/man1" || /usr/bin/mkdir -p "/usr/local/share/man/man1"
/usr/bin/install -c -m 644 'tmux.1' '/usr/local/share/man/man1/tmux.1'
make[1]: Leaving directory `/home/admin/Public/tmux-1.6'
`
