It looks like you don't have autoreconf installed from the fourth line of your stack trace there. Since your using Ubuntu make sure to install it first with sudo apt-get install autoconf here is some more information about that package. Similarly, I had to be sure to install automake for Mac-OS with brew when using the pybtc library.

Edit:
In fact you may want to install automake rather than autoconf. As the documentation for secp256k1-py states: automake is a requirement for Ubuntu/Debian. Autoconf is a dependency of automake anyway so sudo apt-get install automake should work for you
