title: RMySQL installation issue with Mysql 5.5
body: <p>I'm quite new to R, but I've some experience in programming.
  I'm trying to install RMySQL on Windows 7 with MySQL Workbench 5.2 and I keep on getting the same errors. I've already checked different procedures, but keep on getting stuck:</p>

  <p>MySQL is up and running, I have moved libmysql.lib and libmysql.dll, but I keep on getting the following errors. I guess I cannot see the problem for what it really is. Do you have any suggestion?</p>
