Arch, Neovim nightly and jsregexp compilation

[resistorsoftware]

1. I installed Arch Lua51 headers and dev libraries
2. I did a make on the jsregexp library pointing at these libraries using
   make INCLUDE_DIR=-I/usr/include/lua51 LDLIBS=

This built me a jsregexp.so which I assume, is Lua51 compatible. I copy this to the ~/.config/nvim/lua directory so it can be found, and then I fire up Neovim, and issue the command to print(require("jsregexp")) but it still emits the error about undefined symbol: lua_newuserdatauv

I am this kind of stumped as to why the jsregexp module is not being picked up as correct for the LuaSnip? What else do I need to look for here?
