PortSystem 1.0

Name: clisp
Version: 2.47
Category: lang
Maintainers: waqar macports.org
Platform: darwin
Description: The Clisp Common Lisp Implementation
Long Description: CLISP is a Common Lisp implementation by Bruno Haible, formerly of Karlsruhe University, and Michael Stoll, formerly of Munich University, both in Germany. It mostly supports the Lisp described in the ANSI Common Lisp standard. CLISP includes an interpreter, a compiler, almost all of CLOS, a foreign language interface and a socket interface. An X11 interface is available through CLX and Garnet. Command line editing is provided by readline.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/clisp
%  sudo port install clisp  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching clisp
--->  Verifying checksum for clisp
--->  Extracting clisp
--->  Configuring clisp
--->  Building clisp with target all

--->  Staging clisp into destroot

--->  Installing clisp

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using clisp with these commands:

%  man clisp
%  apropos clisp
%  which clisp
%  locate clisp
