As far as security goes, removing the compiler is one of the more useless measures that you often hear about. Whatever means are used to install source files for compilation can instead be used to install the compiler binary itself (or any arbitrary executable).

ruby-build - compile and install Rubies
SYNOPSIS
ruby-build [-v|--verbose] [-k|--keep] definition prefix
ruby-build --definitions
ruby-build --version
ruby-build [-h|--help]
rbenv install [-k|--keep] definition
DESCRIPTION
ruby-build provides a simple way to compile and install different versions of Ruby on UNIX-like systems.
ruby-build downloads, builds and installs the Ruby version specified in a definition into a prefix directory. Definitions can be chosen
from the list of installed definitions or by specifying a file path for a definition.
rbenv(1) users can also use the provided rbenv install command, which installs Rubies into the rbenv directory.
OPTIONS
--definitions
List available definitions.
-k, --keep
Don't delete source code after installation.
-v, --verbose
Display compiler messages on standard output.
--version
Show ruby-build version and exit.
-h, --help
Show usage information and exit.
EXAMPLES
Install Ruby 1.9.3 (MRI, patch level 0) to ~/rubies/mri-1.9.3
$ ruby-build 1.9.3-p0 ~/rubies/mri-1.9.3
Install Ruby Enterprise Edition 1.8.7 (patch level 2011.03) for rbenv(1):
$ rbenv install ree-1.8.7-2011.03
Install Ruby from a custom definition into ~/your-ruby:
$ rbenv install /path/to/your/own/ruby/definition ~/your-ruby
ENVIRONMENT
CC Sets the path to the C compiler.
CONFIGURE_OPTS
Options that are passed to configure when building a Ruby.
