我试图在Mac OS X El Capitan上编译以下ns-2脚本。我使用https://github.com/dhruvvyas90/ns-install-osx

提供的说明安装了ns-2
// Installation steps :
git clone https://github.com/dhruvvyas90/ns-install-osx.git
cd ns-install-osx
chmod +x install.sh && ./install.sh
Restart terminal.

安装正常,因为终端可以使用ns和nam命令。

问题是我无法编译以下脚本:

set val(chan)           Channel/WirelessChannel   
set val(prop)           Propagation/TwoRayGround

我收到以下错误:

我该如何解决这个问题?
