Ubuntu中安装installer3.1失败 help ！

安装installer3.0：
1) ./setup.sh 失败，显示（bash：./setup.sh: /bin/csh:  坏的解释器：权限不够）；
2）安装好了c-shell（apt-get install csh），用root登陆，chmod也试过了，还是显示和1）一样的错误；
3）尝试直接bash setup.sh 显示错误：（行 30： 语法错误：未预期的文件结尾）

大神么教教新手呗，help

#！ /bin/csh -f

if ( ！ $?DISPLAY ) then
    echo ""
    echo "Note: The DISPLAY environment variable is not set."
    echo "      Set this variable to proceed with the graphical"
    echo "      installation."
    echo ""
    exit 1
endif
set cmdpath = "$0"
set cmd = "$cmdpath:t"
if ( "$cmd" == "$cmdpath" ) then
  set cddir = "."
else
  set cddir = "$cmdpath:h"
endif
set cddir_path = $cddir
if ( $cddir_path == "." ) then
  set cddir_path = `pwd`
endif
$cddir_path/installer -gui $argv
