Hi, I’m new to everything so I was just reading this apple page trying to get things set up. [http://developer.apple.com/tools/developonrailsleopard.html](http://developer.apple.com/tools/developonrailsleopard.html) Anyways I get to the “sudo gem update sqlite3-ruby” step after running the first 3 and I get this error… Can someone please give me exact steps to help me correct this. I really don’t have any experience so if you could write things out verbatim it would be really appreciated! HERE IS WHAT SHOWS UP: sudo gem update sqlite3-ruby Password: Updating installed gems Updating sqlite3-ruby Building native extensions. This could take a while… ERROR: While executing gem … (Gem::Installer::ExtensionBuildError) ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb update sqlite3-ruby can’t find header files for ruby.

It does - you can’t compile a native gem like sqlite3 without the developer tools installed and that error message is saying “i couldn’t find some build related things” Fred
