Problem with create_tables.php script

I'm having a problem with my development server. I got all the packages loaded and I'm getting an error during the install. After inputting all the info for the config.php file I would get the following error.

ERROR: Unable to execute query

SELECT * from signup where username='vshare' and pwd='65fc75610940bac2c86f708cb29e2aba'
No database selected

I can connect to the database using mysql client. I've created a db called vshare.

Thanks

What does your config.php file look like?
