Error: guix build xonsh ; guix pull --commit=572ee05c31

[zimoun]

Dear,

I naively try from the Build section in the manual:

guix build \
    --cores=0 --max-jobs=10 \
    --quiet --keep-going         \
    `guix package -A | cut -f1,2 address@hidden

and it does not seem "keep-going" because it quickly fails on xonsh
with the message:

guix build: error: build failed: build of
`/gnu/store/06m5xywkfwza30ngh9lazzaq0vrmwyzr-xonsh-0.6.2.drv' failed


Hum? why not. :-)
I was expecting it works all the night---even more---because the keep-going.


So I `git blame gnu/packages/shells.scm` to see what was the
modification of the file.

Then, I simply try: `git pull --commit=572ee05c31`.
It also fails with the backtrace below. Is it expected?

And `guix descrbibe` tells:
Generation 2 Jan 07 2019 21:10:35 (current)
  guix 912f054
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 912f0541a3b2ae52f3f2d81391f5fbb3161e5625


Well what do I miss?
Is it because I have some export variables twisted?

Last, I am able to find with http://ci.guix.info if it builds
correctly or if the commit 9822835fc8 breaks xonsh.
Is it possible to easily track the build of the commit 9822835fc8 on
http://ci.guix.info?


Thank you in advance for any insights.

All the best,
simon
