Unable to compile version '0.7.0'

[Red]

During a fresh install & new rust project running cargo build, results in the following error message.

error: failed to run custom build command for `lxc-sys v0.5.0`

Caused by:
  process didn't exit successfully: `/target/debug/build/lxc-sys-75c5558466c134fa/build-script-build` (exit status: 101)

All LXC related packages are installed & working.

What am I missing here? C Library, although gcc is installed on my machine?

It appears my system didn't have clang & llvm installed. Compiles successful after these two packages are added to my linux machine.

Readme updates, thank you.
