Compilation of Ruby in the normal way requires a pre-existing ruby
interpreter. Maybe there is a way to compile from scratch - I do not
know. What I generally do on new machines (I use Debian) is first load
Debian's package with

apt-get install ruby

After compiling/installing (under /usr/local as default), you can do

apt-get purge ruby

and happily use your self-compiled interpreter plus utilities.

Remember to install the dev package of libreadline if you want to have
irb command history. Do that before running ./configure.
