IDE 1.6.2 Linux hardware folder is empty

The hardware folder is empty in the linux tar.xz of the IDE 1.6.2 that can be downloaded from the downloads page.
This makes ISP functions to fail, among others.
Comparing with the 1.6.1 compressed file, one can see that hardware contained a "tools" and "arduino" subfolders.
How can one get an IDE 1.6.2 working correctly?
