Mysql gem troubles with Snow Leopard upgrade

I have done everything that is on the web (i think)

i have the new 64 bit xcode that came with snow leopard installed

completely removed mysql, remove开发者_如何学Cd gems compeltely, removed rails installed mysql 64 bit, installed gems, installed mysql gem with the env ARCHFLAGS set

I still get this nasty

NameError: uninitialized constant MysqlCompat::MysqlRes
    from /Users/Navara/Sites/tuosystems/vendor/rails/activesupport/lib/active_support/dependencies.rb:440:in `load_missing_constant'
    from /Users/Navara/Sites/tuosystems/vendor/rails/activesupport/lib/active_support/dependencies.rb:80:in `rake_original_const_missing'
    from /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2503:in `const_missing'

Im not sure how to debug this..

any pointers will be greatly appreciated!

the only thing that i did not reinstall was the problem! RUBY! and doing that fixed it!
