Your system is missing secp256k1_ecdh, one of upstreams optional modules. Install it like this: https://github.com/Bit-Wasp/secp256k1-php/blob/master/.travis.yml#L38

I'll eventually make those functions optional like upstream, but for now we expect the ecdh and recovery modules to be present

Make sure you're using a compatible version of upstream also, see #124
