OSX as a Ruby on Rails dev environment: Package Managers

A lot of Rails developers like to use OSX as their development platform. Although everybody hosts Rails apps on Linux (or Solaris under duress) lots of people love OSX for its productivity, clean interface, and most importantly, its typography.

However, as some have noted, setting up Rails on a mac is hardly a frictionless process. Unlike Linux distros, OSX has no built-in package manager; you get your version of OSX and you get your patches and you'd better like what you get, because every app is going to be updated when Apple or the vendor feel like updating it. This is the same as the Windows world, and it's ugly.

So a couple of efforts have stepped in to fill this void: MacPorts and Homebrew. Neither of these is going to feel like a complete solution if you're used to a package manager like APT or YUM, but they do at least automate the installation process for various open source packages. After all, when you want wget there's no reason you should have to find the website.

I'll start with MacPorts since that came first. MacPorts was inspired by BSD Ports; it is built in Tcl and C and contains a very complete set of available packages. It is quite popular and is the venerable incumbent. And personally, I hate it. I've had my OSX install ruined twice while using MacPorts, just by installing system updates; although I obviously did something wrong, it just isn't a robust solution. If MacPorts is the solution, I don't want to hear the question.

Another alternative is Homebrew, new Ruby-based system developed on Github. It has been around for less than two years, and it's a very active project with a lot of contributors. It stresses extensibility, and lots of recipes have been written to support various packages - predictably, those most popular with Rails developers. Although I don't think it solves the brittleness problem MacPorts suffers (it doesn't address operating system component and library version dependency issues) it is very actively developed, focused on the Rails world, and easily customizable to meet individual needs.

So, although you're probably not going to get set up with a Rails development environment with OSX as quickly as you would on Ubuntu (despite Ruby being included in Xcode), there are good solutions to keep you from pulling your hair all the way out. Which will bring you to the point where you can enjoy and appreciate the kerning on the fonts in TextMate as you write your Rails code.
