According to the web page they have sample applications written in 
Smalltalk and Python.  That would seem to imply that they've wrapped the 
C++ library for use in those languages.  Perhaps you could use Swig 
(http://www.swig.org) to create a wrapper for these libraries so that you 
can access them from Ruby.  This would be faster than a pure Ruby 
implementation which could be advantagous for something like this that is 
mathematically intense.
