Truly, twidge is very simple to install into debian (or derived) linux distribution, I found some problems on centos server but I solved them in a previous article.
Now it's time to install twidge on Mac OS X 10.6.8
To install Twidge on Mac OS X Snow Leopard the following steps shall be performed:
Install the Glasgow Haskell Compiler
Note: this step could take a long time, so be patient!
..........
---> Computing dependencies for ghc
---> Building ghc
---> Staging ghc into destroot
---> Installing ghc @6.10.4_4
---> Activating ghc @6.10.4_4
---> Cleaning ghc
Install Cabal
$ sudo port install hs-cabal
..........
---> Verifying checksum(s) for hs-cabal
---> Extracting hs-cabal
---> Configuring hs-cabal
---> Building hs-cabal
---> Staging hs-cabal into destroot
---> Installing hs-cabal @0.8.0_0
---> Activating hs-cabal @0.8.0_0
---> Cleaning hs-cabal
Update Cabal packages
$ cd /opt/local/var/macports/software/hs-cabal/0.8.0_0/opt/local/bin/
$ ./cabal-0.8.0 update
Config file path source is default config file.
Config file /Users/luigidandrea/.cabal/config not found.
Writing default configuration to /Users/luigidandrea/.cabal/config
Downloading the latest package list from hackage.haskell.org
Note: there is a new version of cabal-install available.
To upgrade, run: cabal install cabal-install
Install Twidge using Cabal
$ cd
$ cabal-0.8.0 install twidge
Now the twidge executables should be in your $(HOME)/.cabal/twidge
Simply type the following command to setup Twidge
$ $(HOME)/.cabal/twidge setup
