No worries, bugs happen.

If you have 'guix' installed, you can run:

  guix build --system=i686-linux --keep-failed gzochi

to reproduce the same build on your machine, and to leave the failed
build directory in /tmp/guix-build-* for further investigation.

Another approach is to run:

  guix environment --pure --system=i686-linux gzochi

to spawn a subshell with environment variables set to mostly reproduce
the build environment used in the "guix build" command above, but
outside of the isolated build container.  If you can reproduce the
problem this way, it should be far more convenient for debugging and for
development of a fix.

If you can fix the problem on i686, please let me know and I'd be glad
to test the same fix on armhf.

What do you think?
