James Duncan Davidson has a great overview article (that needs no further explaining from myself), titled Sandboxing Rails With MacPorts. Another similar article can be found here.

My problem is that I work on a lot of projects that use ImageMagick / RMagick, and that’s not discussed here.

No worries, I’ll install ‘em and give it a go:

sudo port intall ImageMagick
sudo gem install rmagick

CRAP! I don’t know what happens for you, but ImageMagick installs perfectly for me, and then RMagick craps out and dies something like this:

/opt/local/lib/ruby/gems/1.8/gems/rmagick-1.15.9/./lib/rvg/misc.rb:321:in `get_type_metrics': 
unable to read font `(null)' (Magick::ImageMagickError)
 from /opt/local/lib/ruby/gems/1.8/gems/rmagick-1.15.9/./lib/rvg/misc.rb:321:in `render'
 from /opt/local/lib/ruby/gems/1.8/gems/rmagick-1.15.9/./lib/rvg/misc.rb:696:in `text'

Now, for the solution I am going to give all credit to Jakob Skjerning, because I found the solution on his site after doing some Googling.

Do this instead:

sudo port install ImageMagick
sudo port install rb-rmagick

Done. Works. Thank goodness.

What I wanted to comment about here is Apple’s Migration Assistant – which absolutely and undisputedly rocks my little world.

After pondering the long hours I was in for getting all my apps reinstalled, settings, passwords, serial numbers for apps, bla bla bla up and copied and running onto the new Mac – Nick pointed me to the Migration Assistant (which I’m not sure I even really knew about) and off I went. Plugged in my male-to-male FireWire cable into both machines, and booted the MacBook into Target Disk Mode (hold down ‘T’ while powering up until the FireWire symbol displays on the screen). The Migration Assistant asked me what users I wanted, if I wanted the Applications as well, and blammo. I went into the hot tub for a while, and when I got back I had my user, files, documents, library, settings, applications und alles.

So far there are only two apps that didn’t come over seamlessly, and those would be Parallels and Mozy (which, if you haven’t tried, is the best backup software I’ve ever laid my hands on), both of which I needed to reinstall, but after a bit of fiddling are working fine again. All told this thing saved me hours, and I’m sure I’ll use it again on my next Mac purchase.
