Changed for the next release (2.5.5)...

 Optionally install the latest version of Lua in the 5.1.x
 branch, if it isn't already installed on the server and you will be
 using the new Lua engine.

 http://www.lua.org/download.html

 Note that ModSecurity requires the dynamic libraries. These are
 not built by default in the source distribution, so the binary
 distribution is recommended.

Thanks,
-B
