mysql - Unable to start rails server

Question

I have installed rails and mysql. I have also installed mysql2 gem. I created a rails application by the command rails new try_cms -d mysql It was created successfully. But when I try to run the WEBrick server using rails server command I get the following errors.

/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle: dlopen(/Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.16.dylib (LoadError)

Try running this (see similar question here)

sudo install_name_tool -change libmysqlclient.16.dylib /usr/local/mysql/lib/libmysqlclient.16.dylib /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle
