What I remember happening was that on some package I got an error something like "could not get package such-and-such, may be caused by network errors" which wasn't fixed by running the command again. Then I ran with --fallback as recommended, but then it seemed to be building the entire gnome desktop from source. After a few hours of this it was still compiling low-level gnome packages, so I gave up, and the folks at #guix irc suggested guix pull. To be honest, I can't remember which package it was. I'll try again with a fresh installation.
