Corona SDK breaks luasockets on Lua 5.2 ?

have an install of Lua 5.2  I find that after installing Corona SDK Lua 5.2 can no longer require(‘sockets’).  It fails when sockets requires sockets/core.

What I find is LUA_PATH and therefor package.path have been redefined to:

/Applications/CoronaSDK/Corona Simulator.app/Contents/Resources/?.lua;/Applications/CoronaSDK/Corona Simulator.app/Contents/Resources/?.lua;

I don’t understand how this was done since it is not added to my .bash_profile

How can the LUA_PATH be changed without changing .bash_profile?

Is it possible to have 5.2 and the Corona simulator installed simultaneously?
