There are some options which can be tried separately or in combination:
(1) Take a look at the Hudson PVCS VM plug-in and see if it meets your needs. I have not used the plugin.
"This plugin provides integration with Serena's PVCS Version Manager SCM."
(2) Another approach, if you use Ant, would be to use PVCS Ant tasks.
(3) Alternatively, your Hudson job can configure and run the necessary command line actions or call a custom script that does what is needed.
