You can either choose a binary distribution for your platform (to install and use) or get a source distribution (to configure, compile, build, install and use). Please notice that releases 5 and 4 are based on Scheme for the language interpreter and on C/C++ for the geometric kernel of the language. Conversely, the release 3 relies on Common Lisp as the only development environment.
