Gems Gems everywhere!

Today, I set out to upgrade my MacBook Pro to a full fledged dev machine. For this, I added XCode Tools and about a dozen 10 Ruby gems plus ImageMagick which proved to be a bit hairy.

Here we go...

Next, i installed google-geocode but it turns out I didn’t need it so I uninstalled it (Murali ;-) ).

Time for ImageMagick.

See this go to section about Mac OS X binary release.

Download ImageMagick-universal-apple-darwin9.3.0.tar.gz and copy to /Users/roupen or somewhere permanent because you’re going to point environment variables to here.

tar xvfz ImageMagick-universal-apple-darwin9.3.0.tar.gz
rm ImageMagick-universal-apple-darwin9.3.0.tar.gz

You should see a new dir /Users/roupen/ImageMagick-6.4.1

Next, set some env variables

export MAGICK_HOME="$HOME/ImageMagick-6.4.1"
export PATH="$MAGICK_HOME/bin:$PATH"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib"

Run a quick test to make sure ImageMagick is working

Macintosh-2:~ roupen$ cd
Macintosh-2:~ roupen$ pwd

Macintosh-2:~ roupen$ convert
Version: ImageMagick 6.4.1 06/12/08 Q16 http://www.imagemagick.org

UPDATE

I had some problems getting RMagick going – the issue is well covered in discussions on the web. So I backed away from installing image_magic and then the rmagick gem separately. I deleted the image_magic directory and well rmagick never installed.

The NEW path that paid off is described here using rmagick-osx-installer. Search for How do I install RMagick on OS X? on this page for details.

As described in the README for the rmgaick_osx_installer, I first installed XCode Tools and X11SDK off the MacBook Pro DVD. After that, I installed the script and it took a while but it was very uneventful.

libpng was installed successfully
libjpeg was installed successfully
ghostscript was installed successfully
ghostscript-fonts-std was installed successfully
FreeType was installed successfully
libwmf was installed successfully
ImageMagick was installed successfully
RMagick was installed successfully
Removing rm_install_tmp directory...Done

I think I am done. The convert test passed.

I got real close to using MacPorts for this last step but didn’t (felt heavy handed).
