Weird.  Here=E2=80=99s it=E2=80=99s trying to write to the socket correspon=
ding to an
open connection to the daemon.  We=E2=80=99d need to look at the output of
=E2=80=98strace=E2=80=99 to see what happened to this file descriptor.  Can=
 you try
that, if that=E2=80=99s 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,
