Well, as a principle, the Guix package manager runs tests while 
building the package as part of ensuring that the package was 
built correctly. To ensure reproducibility of the builds, 
however, the environment set up cuts away anything that 
introduces variations, network access being one of the major ones.

As such, I need that the tests are run, otherwise the package 
definition will not be accepted (I can't simply cop-out and 
disable all the tests).

To be clear, the building phase completes successfully, but the 
testing phase fails, and Guix requires that all the stages pass 
successfully.
