Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.

I am getting this error for any control I try to drop onto a page from the toolkit. If you try and run the site, you get a "Request for permission of type...." error for any ajax control on the page.
I have tried the repair option of the AJAX Extensions package. I have also uninstalled everything and re-setup the environment per the AJAX Control Toolkit "Setup your environment" page.
Any page using a control has a ScriptManager extension on the page.
I am stuck. Any ideas? Thanks.
