MySQL bindings for Rails 2.3.5 on Mac OS X 10.5.8

I have a rails environment which I set-up with macports. I recently updated macports which seems to have had the side effect of breaking rails. When I try to boot a rails server I get:

$ ./script/server => Boot开发者_运维技巧ing WEBrick => Rails 2.3.5 application starting on http://0.0.0.0:3000 /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. Use #requirement !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. /opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin9/mysql.bundle: dlopen(/opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin9/mysql.bundle, 9): Library not loaded: /opt/local/lib/mysql5/mysql/libmysqlclient.15.dylib (LoadError) Referenced from: /opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin9/mysql.bundle Reason: image not found - /opt/local/lib/ruby/vendor_ruby/1.8/i686-darwin9/mysql.bundle

I've tried reinstalling the mysql gem many times using various configurations I've found around the web but nothing seems to help. Also, when I try to use rake I get:

rake db:migrate Rails requires RubyGems >= 1.3.1 (you have 1.0.1). Pleasegem update --systemand try again.

Even though:

gem --version 1.3.6

What's going on here?

It seems the problem was that I had rails installed under macports, and also as a gem. I uninstalled all the rails components from macports and just stuck with the gems version and it seems to have made the MySQL problem go away.
