See this page

Installation without using packages (raw installation)

• Ruby 1.8 or 1.9 (Ruby 1.6 support was given up to use DateTime)

• NArray: (0.5.7 or later required) a multi-dimensional numeric array class for ruby.

• Misc (ver.0.1.0 or later required) Collection of miscellaneous common basic libraries for Ruby programming.

• Units (ver.1.7 or later required) Class of units of physical quantities.

• NArrayMiss (ver.1.2.4 or later required) a multi-dimensional numeric array that handles data missing.
