Yep. That was it. In fact I had already configured mysql to listen to one of my 
other computers. Didn't think about it that it then did not listen to the 
computer where it was running on.

But now I've ran into the next error:
com.bretth.osmosis.core.OsmosisRuntimeException: The database schema version of 
16 does not match the expected version of 11.

I can find one reference to this on the web, on 
<http://forum.openstreetmap.org/viewtopic.php?pid=10691> it says:
rake db:migrate VERSION=11

but I've got no idea where to execute that command. It's not SQL, and it won't 
run on the unix prompt.
