It looks as though your system is attempting to download and build boost
1.60.0, but both Guix's binary substitute and the original source for
the version are no longer available. Given v0.13.0 is the latest
release, it's a shame if that binary substitute of boost is no longer
available. Not sure why the source would have disappeared.

There is nearly always a way to work around for issues like this, but
given how old your install is, I think you'll save a lot of time by just
reinstalling. There have been quite few breaking changes in the last
year that may catch you even if you do resolve the above issue
(guix-daemon upgrade, Guile upgrade).

For what it's worth, guix is already falling back to fetching the source
from Sourceforge, so I don't think this flag would help you anyway.
