PlanAhead 14.6无法运行

我刚刚在一台运行13.4的机器上安装了ISE 14.6，没有任何问题。
当我尝试从命令行运行PlanAhead时（在运行settings64.sh之后 - 它是64位机器），我得到以下错误。
我尝试了一个干净的Linux安装并在RHEL（实际上是CentOS）6.4和Ubuntu 12.04下尝试了它。
没有找到谷歌的任何信息。
有没有人见过这个？
谢谢，
威利斯

以下为原文

I just installed ISE 14.6 on a machine that's been running 13.4 with no problems.

When I try to run PlanAhead from command line (after running settings64.sh--it's a 64-bit machine), I get the error below.  I tried a clean Linux install and tried it under both RHEL (actually CentOS) 6.4 and Ubuntu 12.04.  Didn't find any information from Google.  Has anyone seen this before?

Thanks,
Willis
