When I run \'rails server\' I get the following error:
Could not find gem \'sqlite3 (>= 0, runtime)\' in any of the gem sources listed in your Gemfile.
I'm summing up in a reply. So :
1) Install macports : http://www.macports.org/install.php - It has a dmg installer, will take 2 minutes.
2) Once you have it installed, do a 'bundle install' and sqlite3 will be installed as specified in your Gemfile.
