yes, it is same PHAT. Chances are that you have python bindings for PHAT
as separate package.

What version of gobject library are you using? Is

engine.c:132: error: expected '=', ',', ';', 'asm' or '__attribute__'
before 'zynjacku_engine_get_type'

the first error you got? Any errors about "unable to include header"?

You cannot run zynjacku without first building the C engine that does
the realtime work.
