The ghc Portfile 42399 2008-11-20 21:02:31Z gwright macports.org $

PortSystem 1.0

Name: ghc
Version: 6.10.1
Revision: 8
Category: lang haskell
Maintainers: gwright
Platform: darwin
Description: The Glorious Glasgow Haskell Compilation System
Long Description: The Glasgow Haskell Compiler is a robust, fully-featured, optimising compiler and interactive environment for Haskell 98, GHC compiles Haskell to either native code or C. It implements numerous experimental language extensions to Haskell 98, for example: concurrency, a foreign language interface, multi-parameter type classes, scoped type variables, existential and universal quantification, unboxed types, exceptions, weak pointers, and so on. GHC comes with a generational garbage collector, and a space and time profiler.

# Yes, it some situations (-fvia-C) we really need perl
# to _run_ ghc, since the mangler (an assembly to assembly transformation)
# is a perl script. That's why it called the "Evil Mangler".

# Not only that, but since correctly handling whitespace is critical,
# only perl 5.8 is known to work reliably.

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

--->  Staging ghc into destroot

--->  Installing ghc

- 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 ghc with these commands:

%  man ghc
%  apropos ghc
%  which ghc
%  locate ghc
