~$ sudo port install jpeg libpng libwmf tiff lcms freetype ghostscript

sudo port install tiff -macosx
sudo port install ImageMagick
sudo gem install rmagick

Hope you got RMagick.

echo $PATH
Make sure the path begins with the MacPorts’ paths like the following
/opt/local/bin:/opt/local/sbin:/bin:/sbin:/usr/bin:/usr/sbin

If not add the following to your ~/.profile or ~/.bash_profile (The shell may use either of this.)

export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export DISPLAY=:0.0

Now save and reinstall the things(Changes to ~/.profile do not take effect on the current shell session. So close and open a new terminal). Everything will go well.
