Answer : SharePoint list template '1101' is not installed in this farm

Hi,
Do you have a folder named PWSIssues in the 12\Template\Features?
I found the blog below where a user encounters similar problems:
http://msmvps.com/blogs/robfarley/archive/2009/07/21/annoying-sharepoint-error-about-features-and-templates.aspx

From these, I would understand that you had some (or all) of the Microsoft templates deployed to your environment and then retracted or they broke, or this site is a restore from an environment where these templates existed.
If either of these are true, then probably you can solve the problems by re-deploying the solution (that would probably be ProjectTrackingWorkspace.wsp from http://www.microsoft.com/downloads/details.aspx?familyid=5807B5EF-57A1-47CB-8666-78C1363F127D&displaylang=en)
But, if none of my suppositions is true, you should try to find what happened, so you don't get into other issues.

Hope this helps
