The gem needs the SQLite development headers in order to compile native code. Having the sqlite3 binary installed (which sqlite3) is irrelevant to the problem.
I'm not overly familiar with Mac but I think you need to install homebrew<http://mxcl.github.com/homebrew/>and then execute brew install sqlite which should install what you need. You'll need to have Xcode <https://developer.apple.com/xcode/> installed before you try installing homebrew. Good luck!
