MySQL gem error after upgrading to Snow Leopard

Question

Just upgraded to Snow Leopard. After much turmoil, I managed to start MySQL and start it.

Now I'm trying to get Rails environments to work. For the project, I use Rails 3.0.3 and Ruby 1.8.7

I installed the MySQL2 gem using the following command:

sudo gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

When I start the rails server, I get the following error:

/Users/lee/.rvm/gems/ruby-1.8.7-head/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle: dlopen(/Users/lee/.rvm/gems/ruby-1.8.7-head/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): no suitable image found.  Did find: (LoadError)
/Users/lee/.rvm/gems/ruby-1.8.7-head/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle: mach-o, but wrong architecture - /Users/lee/.rvm/gems/ruby-1.8.7-head/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
from /Users/lee/.rvm/gems/ruby-1.8.7-head/gems/mysql2-0.2.6/lib/mysql2.rb:7

Has anyone experienced a similar problem and know how to fix it? I am more a designer than a developer, so this will not be my strongest area. Rate any pointers.
