Mixing build systems

[Pronaip]

Hi, I'm (still) trying to build Mininet and it uses both a Makefile for 
building an C executable and setup.py to install its Python modules. I looked 
at the soundconverter package to get some hints for mixing build systems but 
couldn't get very far, I get all sorts of (mostly cryptic) error messages, 
usually about missing modules.
What should I do? I'm pretty new to Guile and Guix but I've packaged software 
for the AUR before.

I attached the code I currently have.

mininet.scm
