I am packaging ldc for NixOS and I was having the same problem 
there.
I solved it by putting the tests with special needs into a fixed 
output derivation.
That's how it is called in Nix world. Fixed output derivation's 
always produce the same output and are therefore allowed to 
access the network. They are also used to implement all kinds of 
fetchers to get the source archives from GitHub and the like.
guix sure has something equal because it basically is the same 
system. They even use parts of Nix.

Here you can take a look into the current package:
