I'm assuming your Raspberry Pi has the Hamachi client configured and already. If I'm correct, when you SSH into your Pi and do something like "sudo hamachi", your console says something like "Hamachi doesn't seem to be running" or something along those lines.
In that case, what I did was I edited the /etc/sysctl.conf file by doing
sudo nano /etc/sysctl.conf
Then at the bottom of that file, add this line:
net.ipv6.conf.ham0.disable_ipv6 = 0
Reboot afterwards. I may advise doing a clean install of Hamachi on your Pi and doing this step before commanding a reboot.
