As of yesterday, Hamachi 2.1.0.101 is now available. I have tested a plain version bump of the ebuild in my personal overlay and it works well (tested connecting to a remote machine over the resulting hamachi tunnel). Reproducible: Always
I shall add that the current version is not downloadable anymore.
