it appears to be this bug:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35743

It's marked in the hackage.scm to expected fail, but the layout problem
with cabal files seems pretty ubiquos. I'll try to look at it, and move
the discussion there.

If anyone can give me some tip to how start debugging the test, I'll
appreciate it, since I'm pretty new in scheme hacking with guile in
guix. I must be overlooking something very obvious.

Thanks.
