sqlite3-ruby-1.2.2 is broken on OS X

So I just spent ages trying to figure out why the latest version of sqlite3-ruby wouldn’t run on OS X. Turns out there is a bug …

If you are getting an error that looks like:

dyld: NSLinkModule() error
    dyld: Symbol not found: _RSTRING_PTR
      Referenced from: /usr/local/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.2/lib/sqlite3_api.bundle
      Expected in: flat namespace

    Trace/BPT trap

Its best to revert back to 1.2.1 which seems to work fine. This behavior occurs on Tiger and Ruby 1.8.4.
