pgRouting (http://pgrouting.postlbs.org/) uses the alpha-shape algorithm
of the CGAL library for its driving distance calculation. This is not
the perfect solution, because this part of CGAL is released under QPL,
which is in general incompatible with GPL ... except you are the
copyright owner and add an exception.
http://www.cgal.org/license.html --> see GPL-QPL Incompatibility Note
If possible I would avoid using CGAL.
It can be also annoying to install (my personal experience).
