ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) -- I never set a password (no replies)

I've been trying to set up mysql on osx 10.6.5 for two days now using macports. I finally got past the mysql_install_db error, now I can't get past this one:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

Ha! I never even set a password for mysql. I've installed and used mysql before with no problems, should I switch back to postgresql?

Thanks,

Jason
