[Freeswitch-users] Version of Lua with FS1.4

[Alex Lake]

I installed FS1.4 on an Ubuntu14.04 box the other day and found that it 
seemed to be using Lua5.2. After hunting around for a bit, I managed to 
find Lua 5.2 versions of the modules we use.

I then wiped the machine and attempted another build, and it used Lua 5.1!

I'm confused as to what I've done differently. Is there a preferred Lua 
version for 1.4?
