Subject: Regex help

Hello list!
     Could someone help me do a little regex conversion? I've got a  
few perl compatible regexes from a php script I am trying to port to  
ruby but I need a little help. Here are the php functions:

  $buffer = preg_replace("#(?<!\"|http:\/\/)www\.(?:[a-zA-Z0-9\-]+\.)* 
[a-zA-Z]{2,4}(?:/[^ \n\r\"\'<]+)?#", "http://$0", $buffer);
  $buffer = preg_replace("#(?<!\"|href=|href\s=\s|href=\s|href\s=) 
(?:http:\/\/|https:\/\/|ftp:\/\/)(?:[a-zA-Z0-9\-]+\.)+[a-zA-Z]{2,4} 
(?::[0-9]+)?(?:/[^ \n\r\"\'<]+)?#", "<a href=\"$0\" target=\"_blank\"> 
$0</a>", $buffer);
$buffer = preg_replace("#(?<=[\n ])([a-z0-9\-_.]+?)@([^,< \n\r]+)#i",  
"<a href=\"mailto:$0\">$0</a>", $buffer);

Can someone please help me get these into a format that ruby will  
like? I kow I will end up using gsub! to do the sub but these regexes  
don't parse correctly in ruby and I am not sure of the rules I need  
to follow to make ruby happy. Help is much appreciated.
Thanks-
