Is the order in which you list your gems important? Are these two blocks equivalent?
gem \'carrierwave\'
gem \'rmagick\'
And
When you use Bundle.require
(which Rails does), Gems are required in the order they appear in the Gemfile. In wasn’t always like this, but has been this way for a while.
Since Carrierwave requires RMagick explicitly when it is needed, I don’t think it should matter in your case; but strictly speaking the two blocks are not equivalent.
