if you're not using postgres and using mysql, you can simply comment this lines

# Database gems
#platforms :mri, :mingw do
#  group :postgresql do
#    gem "pg", ">= 0.11.0" 
#  end

#  group :sqlite do
#    gem "sqlite3" 
#  end
#end

You can skip gems you don't need using bundle's "--without" option.
E.g. if you don't want to use PostgreSQL, you can simply run

bundle install --without=pg

If you use sqlite for example, and don't use openid and rmagick, use

bundle install --without=test pg mysql2 mysql openid rmagick

However, if you do want to use PostgreSQL, install it first using

gem install pg -- --with-pg-lib=/opt/PostgreSQL/9.1/lib --with-pg-config=/opt/PostgreSQL/9.1/bin/pg_config
