Stack traces I get when I attempt to install native Ruby extensions on OS X 10.8 Mountain Lion Developer Preview

Trying to make my Ruby environment happy under OS X 10.8 Mountain Lion

A few notes. I had:

  • installed XCode 2.4 Preview as well as its command line tools (which are found separately in Preferences -> Downloads)
  • updated rvm (rvm get latest)

and my issue was:

  • system ruby installed every gem with native extensions I threw at it
// jquery invert plugin
// by paul irish
// some (bad) code from this css color inverter
// http://plugins.jquery.com/project/invert-color
// some better code via Opera to inverse images via canvas
// http://dev.opera.com/articles/view/html-5-canvas-the-basics/#insertingimages
// and some imagesLoaded stuff from me
