Build fails on Ubuntu 14.10 x64

[rjpcomputing]

I cloned the repo and tried to build using ./build and I am not able to build luaposix.

Any ideas what is going on. I used LuaRocks to install LuaPosix on this machine, so I feel like I have the development libraries needed.

Let me know if there is any other information you need.
