Hi Thiago,

In fact it is happening when I make a  high energy physics python package 
(matplo/heppy on GitHub). I narrowed down the issue to the inability to 
download the file and so wrote the CMakeFile.txt that I sent you to isolate 
that issue. In fact I had the idea you mentioned of the LOG file. However when 
I put that command it, it didn't seem to work.

How do you specify a LOG file with the FILE command ?

Note that all the compilation works if I do it in a Docker container on my Guix 
laptop (with Debian base).
