When I try and run a RAKE on Webistrano I get the following error:
undefined method `name' for "actionmailer":String`
I am a not proficient in Ruby and RoR but I have installed and played about with plenty of applications before and I can’t find what the issue is.
The command I am running is:
RAILS_ENV=production rake db:migrate --trace
Which produces the below:
I would really like to know the best way to diagnose and fix this issue and issues like it in the future.

When I run ruby -v I get the following:
ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]
This worked for me.
