My colleague has another installation instructions on OS X 10.4 (Tiger).

But for you lucky Leopard users here are a few easy steps you can take to install the RMagick Gem on OS X (Leopard).

Install developer tools

Leopard Install DVD > Optional Installs > Double Click ‘Optional Installs.mkpg’

If you do not install the developer tools you will not be able to continue.

Install Macports

http://darwinports.com/download/ > Double click ‘MacPorts-1.5.0.pkg’

Update Macports

Open a new terminal window.

$ sudo port -d selfupdate
Password:

Install Tiff Library And ImageMagick Executables

The tiff has to be installed with a special provision. If you just install as is you would get errors because of the OpenGL subsystem. So to avoid this problem you type in the same terminal window:

$ sudo port install tiff -macosx
Password:

Then:

$ sudo port install ImageMagick

And of course you may want to finish off with the rmagick gem itself!

$ sudo gem install rmagick
