Why is this RMagick call generating a segmentation fault?
I've been banging my head against the wall for the better part of an hour trying to figure out what's going wrong here, and I'm sure (or rather hoping) it's something fairly obvious that I'm overlooking. I'm using Ruby 1.9.1, Sinatra 1.0, and RMagick 2.13.1. ImageMagick and RMagick are correctly installed and functional—I've successfully manipulated and saved images from irb. The relevant part of

Installing RMagick on OS X using MacPorts
Revised 16Nov2007 This page describes a method for installing RMagick, ImageMagick, and the delegate libraries used by ImageMagick. I developed this procedure using a clean install of OS X 10.5 (Leopard) on a PowerPC PowerBook G4, but the procedure should be the same for Tiger and Intel Macs. You will need to have your OS X installation disk, a connection to the Internet, and at least an hour of f
