我将 lua 包安装到 Textmate，但是当单击“检查语法”时，我收到此错误：
Unable to locate luac
To succesfully run this action you need to install «luac». If you know that it is already installed on your system, you instead need to update your search path.
The manual has a section about how to update your search path.
For diagnostic purposes, the paths searched for «luac» were:
/usr/bin
/bin
/usr/sbin
/sbin
我可能正确安装了 lua，当我将“lua”写入终端时，我会得到：Lua 5.1.4 版权所有 (C) 1994-2008 Lua.org, PUC-Rio
我正在运行 Mac OS X Lion 10.7.2
哪里有问题？谢谢你。
