How to build the type-nats branch

[Iavor Diatchki]

Hello,
aha, I'll try to fix this some time this week, I hadn't noticed that it was
broken. It is probably because the `type-nats` branch has not been merged
with `master` in a while, so there are discrepancies between the versions
of the compiler and the libraries.
