Fails how?

The SRFI-64 log files of the failing tests, plus test-suite.log. Test
failures must not remain uncorrected! ;-)
When there are so many failures, it’s likely that there’s a setup issue,
like socket names are too long.

What Guile and libgc version is this, and what platform?

That seems similar no?
Does the installation seem sane, basically? Do ‘guix build’, ‘guix
package’ etc. work somehow, or not even?

There’s a local cache of substituter hits/failures in
/var/guix/substitute-binary (or similar.) When that cache is empty or
outdated, a lot of HTTP queries are made to hydra.gnu.org, which can
take a bit of time.
When using a recent Guile, these queries are made in parallel. On my
machine, it goes like this:
--8<---------------cut here---------------start------------->8---
$ sudo rm -rf /var/guix/substitute-binary/cache/
$ time guix build emacs -n
real 0m30.551s
user 0m2.519s
sys 0m0.154s
$ time guix build emacs -n
real 0m3.381s
user 0m2.039s
sys 0m0.123s
--8<---------------cut here---------------end--------------->8---
The cost is high when starting from an empty cache, but afterwards it’s
small.

Add call to ‘show-build-options-help’ from (guix scripts build).

Remove this option, and concatenate with ‘%standard-build-options’.

The extra value gets truncated here, so it’s not strictly needed.
Thanks!
