I have never seen the installer telling you that MySQL would be unusable, while it in fact is working. I guess that when you debug (How to debug) your particular error, you will notice that it in fact originates somewhere in a database issue.

What exactly does phpinfo tell inside the section on MySQL? In fact I think that MySQL is not usable currently for you.
