I'm on OS X Snow Leopard, I have installed MySQL using the OS X packages found on the MySQL download website, Ruby 1.8.7 from source code (which ruby yields usr/local/bin/ruby only) and RubyGem 1.7.1 (upgraded from 1.3.1 using gem update --system) from source code too (after updating gem I re-ran gem update). The start/stop MySQL server prefpane is installed, too.

After this I have installed the rdoc, mysql and mysql2 gems using gem install rdoc, gem install mysql and gem install mysql2, in this order.

After creating a sample project, I modified the database.yml so that mysql is the db used instead of sqlite3.

Then, I cd into the project folder and run rails server with the following error:

sample$ rails server /usr/local/lib/ruby/gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle: dlopen(/usr/local/lib/ruby/gems/1.8/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.18.dylib (LoadError)

What's wrong with my configuration? I read that there are files to rename (?) but I did not understand how. Thanks very much in advance to everybody Riccardo

This looks similar (if not identical) to this problem. There are a number of possible solutions on that question.
