• Install libsodium http://doc.libsodium.org/installation/README.html
• Install libtoxcore (libtoxav and the DNS client are not required) https://github.com/irungentoo/toxcore/blob/master/INSTALL.md
• git clone https://github.com/gjedeer/tuntox.git
• cd tuntox
• make

The makefile creates a static binary by default. If you're not a fan of static binaries, remove "-static" from LDFLAGS. One reason to do so may be if you'd like to resolve hostnames on the tuntox server (invoke client with -L 80:reddit.com:80 instead of -L 80:198.41.208.138:80). Static linking breaks hostname resolution, but IMHO the pros overweight the cons.
