I found it not really straightforward to get Pugs up and running on my PowerBook, so I thought I'd share some installation instructions that worked for me. These instructions refer to GHC 6.4.1, hs-plugins as of 2005-09-24, parrot 0.2.3 and Pugs 6.2.9. Make sure you adapt the paths mentioned as needed.

Install parrot

This will enable parrot support in Pugs. Plus, who doesn't want a parrot?

• Download parrot
• Copy the parrot-0.2.3 directory to /usr/local (the built parrot will remember its path, so choose someplace where you can leave it, not a temporary location)
• perl Configure.pl
• make
• make test

Install DarwinPorts

DarwinPorts is needed to install GHC

• Download the binary installer for DarwinPorts (right now, version 1.0)
• Edit your ~/.profile, add the paths mentioned in the installation package. E.g.

  # add the DarwinPorts path behind the standard path, so the
  # perl installed by DarwinPorts will not override your system perl :(
  export PATH=$PATH:/opt/local/bin
  export MANPATH=/opt/local/share/man:$MANPATH
  export INFOPATH=/opt/local/share/info:$INFOPATH
  

• sudo port -d selfupdate

Install GHC

The Glasgow Haskell Compiler is needed to compile Pugs

• sudo port install ghc. This will take quite a long while.

Install darcs

Darcs is a revision control system needed to retrieve hs-plugins

• sudo port install darcs

Install hs-plugins

This is a GHC plugin that is needed for Pugs' parrot support

• darcs get http://www.cse.unsw.edu.au/~dons/code/hs-plugins
• Change into hs-plugins directory and runhaskell Setup.hs configure
• runhaskell Setup.hs build
• runhaskell Setup.hs install
• I don't know why, but I had to do sudo ranlib /usr/local/lib/plugins-0.9.10/libHSplugins-0.9.10.a.

Install Pugs

• Download Pugs
• export PUGS_EMBED=perl5,parrot
• export PARROT_PATH=/usr/local/parrot-0.2.3
• Edit Makefile.PL: Remove the error message that GHC 6.4.0 won't work with GCC 4 (since we installed GHC 6.4.1)
• perl Makefile.PL
• make (again, this takes quite a while)
• make install

Et voilà!

$ pugs -e 'say "Hello, World!"'
Hello, World!
