Building Ruby, Rails, Subversion, Mongrel, and MySQL on Mac OS X Tiger – The Easy Way

“Dan Benjamin”: recently updated his very helpful article entitled “”Building Ruby, Rails, Subversion, Mongrel, and MySQL on Mac OS X”:”.

I don’t know about anyone else but compiling software is not one of my favourite pastimes. As I’ve been chopping and changing macs lately I thought I’d write a couple of shell scripts to get things right before running anything on my nice new (freshly installed) MacBook Pro.

h3. Prerequisites

There are a couple of prerequisites in addition to what’s on Dan’s “”What’s Needed”:” list before running “the scripts”: The first is that you must have MySQL installed as referenced in “Dan’s article”:, and the second being the following:

Ensure you have the following line at the end of your ~/.bash_login file:

export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

You can add this by typing nano ~/.bash_login then copy and paste the above line into the end of the file. Once this is done, hit ctrl-x to exit, answering ‘y’ to “do you want to save changes” prompt.

h3. The scripts

There are two scripts, “”: and “”: and the following will explain how to use them.

h3. Creating your development environment

The first script will install everything in Dan’s article along with the following gems that I use frequently:
* rails version 1.1.6 for support of older rails apps
* bluecloth
* redcloth
* sqlite3-ruby
* ferret
* ZenTest
* redgreen

Right… here we go:

(please read “the licence”: before running these scripts as although they have been tested on a clean install of Tiger, I can’t take any responsibility if something breaks)
# Download “”: to your desktop
# If you don’t wish to install all of these gems then open the file in a text editor and comment out the relevant lines with a hash.
# Open a new terminal window and type the following:

cd ~/Desktop

# Go make a cup of tea and watch all the pretty text scroll before your eyes.

That’s it, you should now have a fully working development environment.

h3. Image tools

I use a couple of image tools on my system, GD and ImageMagick (with RMagick). If you wish to install these tools and the related libraries, run the following:

(This script hasn’t been tested as much as the previous one so use at your own risk. If anyone has any bug fixes then please post a comment)

cd ~/Desktop

h3. We’re done

Please let me know if I’ve missed anything obvious.

I hope this helps anyone else out there with Compilaphobia!
