I managed to find the prerelease packages in the build scripts, and got it working through that. Make sure you restart the keybase service, as it doesn't happen automatically

I love you.
EDIT: Still doesn't work, unfortunately. I get the /keybase dir, but it's empty.
This needs to be more visible in this thread.
By the way, how did you manage to install Keybase FS? It won't work for me at all.
