What this ruby script does:

1. Installs build dependencies for Ruby.
2. Downloads ruby source tarball using the version listed in the constant VERSION
3. Untars the tarball, configures the build, runs make and make install, Ruby is installed on the system as root, no version manager (RVM, rbenv, chroot) is used.
4. Cleans up the tarball and build directory by removing them.

Assumptions:

1. Raspberry Pi is accessible by ip or host name.
2. Raspbian, Raspbian lite, or ubuntu derivative OS that supports APT packages is already installed.
