[support] Unmet dependencies??

Folks: A status report message is: "Some modules have database schema updates to install. You should run the database update script immediately." When I do update.php, that says: "Warning message Some of the pending updates cannot be applied because their dependencies were not met." Then, the message: "No pending updates" How should I approach this? Ignore it? Find out more? Sounds like there is some problem with the database. Is there a way to diagnose this?
