I'm asking you to run otool on the Qt MySQL plugin. The path I've used in the command samples are meant to be replaced by the actual path to where the plugin is located. I don't know where it is on your system, so don't just copy paste the command, update it as well.

@SGaist Sorry was 3 am. Deleted that comment as soon as I knew what I did I updated it immediately though with the correct path ^

/opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)Here's your problem... It is looking for mysql in the /opt/local/lib directory (which is a weird directory), when according to your post above it is in /usr/local/opt/mysql.
Usually people use /usr/local or /opt. I've never seen /opt/local. But it's not like there's set rules for directories or anything, so to each their own.
Anyway use
otoolto fix those paths and it should work. -
It's not weird for tools that are external to the distribution if we talk Linux style.
In this case, it's macports that is using it like that.
In any cas, the parameters passed to install_name_tool must be correct there's no error message telling you that the paths are invalid.
