Also, I found part of the answer to my problem. FreeSWITCH Lua was updated to 5.2 on Nov 12th, 2771498707c194c70cf25ad9473be66ef59cfb46, so I went ahead and grabbed the corresponding LuaXml library for version 5.2 not 5.1.</div>

<div><br></div><div>I already followed the instructions in <a href="http://wiki.freeswitch.org/wiki/Mod_lua" target="_blank">http://wiki.freeswitch.org/wiki/Mod_lua</a> for installing LuaXml via the luarocks package manager, so since that didn't work I tried including the library manually from the luaxml website.

<div><br></div><div>I also tried recompiling from scratch running the bootstrap and configure scripts. No luck.</div><div><br></div><div>I've also tried installing both Lua 5.1 and Lua 5.2. I realize the wiki shows 5.1 being used, but I already tried that and moved onto trying other things. Still working on trying to figure out what happened, but wanted to see if anyone else is having any trouble with this as well. I realize Lua is embedded in FreeSWITCH, so I'm a bit confused about why it can't find the library.</div>
<div><br></div><div>Using lua 5.2 on the box, I can run the test.lua script that users the library, what version of Lua does FreeSWITCH use? I'm not convinced it's using an embedded version of Lua based on the fact that I see it trying to use the paths from the Lua installed from apt-get.</div>
