Answer 1

The installation page tells you what dependencies you need. This one is fulfilled by:

sudo apt-get install libssl-dev

---

This is already packaged in trusty/universe (version 1.0) so if dependencies haven't changed that much a good tip can be to just let apt-get build-dep help you:

sudo apt-get build-dep aircrack-ng

That will download all the dependencies required to build the repo version. Might not be everything you need but it should get you most of the way.
