There seems to be enough people struggling with getting a Haskell interpreter working on Mac OS that I’ve decided to write up step by step instructions.  This is how you install the hugs Haskell interpreter.

  1. Get Fink from http://www.finkproject.org/download/index.php?phpLang=en
  2. Open the file you downloaded and, then double-click the “Fink [...] Installer.pkg” package inside (where [...] is whatever the latest version of Fink is at the time you go there). Follow the instructions on screen, defaults for everything is good, accept the installing of the path stuff.
  3. Open Terminal (just type Terminal in Spotlight)
  4. Type fink install hugs [enter]
  5. Enter your password
  6. You may be asked if you want to install something that hugs uses… just press Y and enter
  7. Voilà!  You’ve now got hugs installed.

To use hugs in the future just run Terminal and type hugs [enter].  That’s it.
