fedora8安装xfce4的问题

f10装的有问题，只好转到f8了。现在f8下面装xfce4。先去下了一个xfce4-4.4.3-installer.run/，用./xfce4-4.4.3-installer.run开始安装，结果出了问题：

./bootstrap.sh: line 199: 637 段错误 ./installer-gui >> ${INSTALLER_LOGFILE} 2>&1
failed, see /home/luwei/.xfce4.installer-log for details

不知道怎么解决？安装不成功，我只好yum了一个，yum install xfce4*.yum
好了，之后怎么启动xfce4呢？用startxfce4启动不了
