The gambit-c Portfile 54924 2009-08-04 18:41:22Z snc macports.org $

PortSystem 1.0

Name: gambit-c
Version: 4.4.4
set branch [join [lrange [split ${version} .] 0 1] .]
Category: lang scheme
Platform: darwin
Maintainers: gmail.com:arto.bendiken
Description: Gambit-C is a fast Scheme implementation.
Long Description: Gambit-C includes a Scheme interpreter and a Scheme compiler which can be used to build standalone executables. Because the compiler generates portable C code it is fairly easy to port to any platform with a decent C compiler. The thread system is very efficient and can support millions of concurrent processes. The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards. The full numeric tower is implemented, including: infinite precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers.

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/gambit-c
%  sudo port install gambit-c  
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 gambit-c
--->  Verifying checksum for gambit-c
--->  Extracting gambit-c
--->  Configuring gambit-c
--->  Building gambit-c with target all

--->  Staging gambit-c into destroot

--->  Installing gambit-c

- 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 gambit-c with these commands:

%  man gambit-c
%  apropos gambit-c
%  which gambit-c
%  locate gambit-c
