安装Synopsys DC的license时的问题，请高手解答！

在ubuntu 9.10下安装synopsys dc2009.06，
生成的synopsys.dat已经用sssverify验证通过，但是在用lmgrd -c synopsys.dat命令启动license时，有如下结果：
22:22:58 (lmgrd) The license server manager (lmgrd) running as root:
22:22:58 (lmgrd)     This is a potential security problem
22:22:58 (lmgrd)     and is not recommended.
22:22:58 (lmgrd) Can't make directory /usr/tmp/.flexlm, errno: 2(No such file or directory)
22:22:58 (lmgrd) Can't make directory /usr/tmp/.flexlm, errno: 2(No such file or directory)
22:22:58 (lmgrd) Can't open /usr/tmp/.flexlm/lmgrdl.1999, errno: 2
22:22:58 (lmgrd) Failed to open the TCP port number in the license.
22:22:58 (lmgrd) Can't remove statfile /usr/tmp/.flexlm/lmgrdl.1999: errno No such file or directory

导致license无法启动，请高手帮忙看看，这到底是什么原因引起的？
非常感谢！
