You can create multidimensional array just the same:

[
  ['rm something','Error I could'nt remove something'],
  ['apt-get install thishere','Error while installing the packet'],
  ['module-assistant a-i mymodule','Error while installing the module'],
].each do |cmd, error|
  unless system cmd
    $stderr.puts error
    exit 1
  end
end

Kind regards
