Hi,
Just saw this update, and tried it out. Everything compiled a few days ago., but today I got "undefined reference to `luaload_network(lua_State*)'"

I saw your commit, and just wondered if....

rm -rf corona
git clone --recursive git@github.com:coronalabs/corona.git
cd corona
cmake .
make

Just in case, I will clone the repo again from my fork, and will roll back

Hello, I just deleted my clone / synced my fork and cloned that fork.

git clone --recursive git@github.com:HBL001/corona.git

So I suspect, your "network issues fix" breaks something in NetworkLibrary.cpp, maybe only for the Linux build.

Apologies for being a nuisance !
