wget download getting 404 (no replies)

Hi, I'm on CENTOS trying to download mysql using the command line. The command line I use is: wget http://dev.mysql.com/get/Downloads/MySQL-5.5/MySQL-5.5.19-1.linux2.6.i386.tar/from/http://mirror.csclub.uwaterloo.ca/mysql/

And I get

Resolving dev.mysql.com... 156.151.63.11
Connecting to dev.mysql.com|156.151.63.11|:80... connected.
HTTP request sent, awaiting response... 404 Not found
2012-01-09 11:28:53 ERROR 404: Not found.

Is there a reason why i'm getting a 404? I've tried using other url from the download web page but I still get a 404.

Thanks,
Pat
