I defined a new package, python-conda, and tried to build with the
command `./pre-inst-env guix build --rounds=3 python-conda`

I expected that the package would have built successfully, instead,
the build fails with the message:

output ‘/gnu/store/302bb93kq3170xr57vijil7cya2s74ir-python-conda-4.3.16’

differs from ‘/gnu/store/302bb93kq3170xr57vijil7cya2s74ir-python-conda-4.3.16-check’
from previous round

guix build: error: build failed: build of
`/gnu/store/wgih8s8x0bpgxyk7vwyxr4r3wl0y1vfa-python-conda-4.3.16.drv'

I would appreciate any pointers on how to resolve this issue.

I have attached the definition of python-conda and the full build log.

I have also attached the definition of python-ruamel.yaml, which is
already submitted to guix-patches@gnu.org, and is awaiting moderation.
