NS2安装过程中环境变量设置的问题（ns-2.35）

nam: Can't find a usable tk.tcl in the following directories:

在安装ns2的过程中遇到这个错误，在查找了很多资料后才找到解决问题的办法：
在TCL_LIBRARY中添加值$NS_HOME/ns-allinone-2.35/tk8.5.10/library
即修改TCL_LIBRARY为TCL_LIBRARY=$NS_HOME/ns-allinone-2.35/tcl8.5.10/library:$NS_HOME/ns-allinone-2.35/tk8.5.10/library
然后source ~/.bashrc
其中$NS_HOME是ns2的路径

下面附带我的环境变量设置：

export NS_HOME=/data/ns2/ns-allinone-2.3.5
export PATH=$NS_HOME/bin:$NS_HOME/tcl8.5.10/unix:$NS_HOME/tk8.5.10/unix:$PATH
export LD_LIBRARY_PATH=$NS_HOME/otcl-1.14:$NS_HOME/lib
export TCL_LIBRARY=$NS_HOME/tcl8.5.10/library:$NS_HOME/tk8.5.10/library
