Has anyone encountered the following error when running

make pdk

on the mpw-5b tag?

Removing temporary files from destination.
Done with PDK migration.

This is due a very old git version (1.8.3.1) used in the Magic docker image, if you manage to upgrade it to a newer one, and you add "-v $(PDK_ROOT):$(PDK_ROOT)" to the docker invocation in the "caravel/Makefile" it will be fixed. Alternatively you could call the make cmd with sudo and let the involved pdk files with root ownership.

Thanks for the feedback. The changes to the Makefile were enough to resolve the issue.
