Does require\_gem also load all of the listed dependencies in the gem
spec or are those dependencies loaded by manually through require
statements?
so example:
require\_gem 'rails'
the rails gem has:
actionwebservice
actionmailer
actionpack
activerecord
activesupport
rake
as listed dependencies.
so does require\_gem 'rails' also perform require\_gem 'actionamailer',
etc... ? or is there a specific 'require' statement somewhere in 'rails'
?

require\_gem is only useful for picking a particular version of a gem. If you don't manually specify the version of the dependent gems (in dependency order) you'll get whatever their gemspecs need.
