Hamachi is a proprietary application, more precisely: a VPN Service client.
See there for more details:

In other hand,
GLIBC 2.26 is what the slackware-current ships today.
Long story short, that Hamachi thing looks like not being compatible with our Slackware current.
I suggest to OP to go back to a stable version, i.e.
Slackware 14.2, if he want stability and usability.
