Weird.  Here’s it’s trying to write to the socket corresponding to an
open connection to the daemon.  We’d need to look at the output of
‘strace’ to see what happened to this file descriptor.  Can you try
that, if that’s easily reproducible?

Note that you can get pre-built binaries for x86_64-linux from
hydra.nixos.org:
<http://lists.gnu.org/archive/html/bug-guix/2012-11/msg00042.html>.

Yes, I agree this would be nice.  It can be achieved by tweaking
guix/build/download.scm and related code.

Thanks,
