Check it out (pun intended...):
FinalBuilder now has very comprehensive integration for IBM/Rational ClearCase. The actions support both ClearCase Base and UCM to do anything you'll need to do in an automated build process! And if there happens to be some particular ClearCase operation which isn't covered, you can use the “ClearCase Run Cleartool (Generic)” action which allows you to specify the exact command line parameters to use with cleartool.
So, this really starts to round out the support for version control systems in FinalBuilder. Currently in development is integration with Microsoft TeamSystem and JediVCS (hang in there if you're waiting for this!)
