linux(centos)环境下安装IDL7.1后出现错误error

ireneliang2010

最近在学习Geos-Chem模式，在linux下安装IDL7.1的时候很不顺利。小妹求助各位前辈！
在服务器目录/usr/src/itt/下安装成功后，我作为用户登录并调用的时候出现了两个错误。见下方：
[ireneliang2010@inode1 ~]$ idl
/usr/src/itt/idl71/bin/bin.linux.x86_64/idl: error while loading shared libraries: /usr/src/itt/idl71/bin/bin.linux.x86_64/libfreetype2_3_6.so.6: file too short
[ireneliang2010@inode1 ~]$ idlde
-bash: /usr/src/itt/idl71/bin/idlde: Permission denied
我的安装参考文章来自于网页http://www.xker.com/page/e2007/0913/34118.html，在进行到第九步时存在一个小提示，不过应该没影响。
还希望各位有经验的大神么，能够帮助我解决疑惑。我将非常感谢。希望有同样困惑的童鞋么，也可以帮我顶一下！

我重新安装了IDL8.2，参考帖子http://blog.sciencenet.cn/home.php?mod=space&uid=287062&do=blog&id=692527安装成功。但是作为用户登录服务器后运行idl，显示：

是不是说明license没有成功？还希望各位有经验的大神么，能够帮助我解决疑惑。我将非常感谢。希望有同样困惑的童鞋么，也可以帮我顶一下！
