my initial thought was just to output them plainly :)
my stupid example follows,

botp@pc4all:~$ cat test.rb
v0=nil
File.open("test.txt").each_line do |lines|
  values = lines.chomp.split(",")
  if v0 != values[0]
    puts unless v0.nil?
    v0 = values[0]
    print v0
  end
  print ",",values[1]
end

botp@pc4all:~$ ruby test.rb
bla@bla.com,value1,value2,value3,value4
ruby@ruby.br,value1,value2
