for clang _tracking_rect is package private, so it should not be visible in 
ProjectCenter. This shouldn’t be an issue as the code using it was removed from 
ProjectCenter two years ago. But somehow the package you are using still seems 
to include that old code. Looks like we need a new release of ProjectCenter. 
Until that happens you are best off by using the code from git.

Hope this helps,
Fred
