Are these "errors" OK during the installation?

I received these "errors" on the last page of the install after I had a few other problems I resolved:

Error: Table 'pp_usergroups' already exists
Error: Duplicate entry '5' for key 1
Error: Duplicate entry '1' for key 1
Error: Duplicate entry '3' for key 1
Error: Duplicate entry '4' for key 1
Error: Duplicate entry '2' for key 1

Strange thing is that after I resolved all the other problems, I went a head and deleted my mysql database and recreated and ran the install again, yet it still says on some of those top lines and the page that appeared before this one a bunch of duplicates. Don't really understand how there could be dups if I recreated the database. Anywho, are all these lines alright for me to use this installation?

Thanks.
