Problems with gobject-introspection upon install

[fritzy]

In Ubuntu 16.10, I've installed all of the dependencies listed in the README, and attempted to install a dependency of lgi. The ubuntu package of lua-lgi appears to be older than what you want.

I don't know how things are setup on ubuntu, but these are the two packages I need to have installed for lgi to build:

There's probably a dev version of gobject introspection that you're missing

I ended up searching for which package contained the "pc" file and found libgirepository1.0-dev

Thanks!
