[Nicolas Graves via Guix-patches via <guix-patches@gnu.org>]

* gnu/packages/python-science.scm (python-pandas): Update to 2.1.1.
[source]: Use git origin.
[build-system]: Use pyproject-build-system.
[arguments]:
  (modules): Remove argument.
  (test-flags): Add required test flags.
  (phases): Add phase version-set-by-guix and pre-check.
  Remove phase enable-parallel-build. Remove check phase
  replacement.
[propagated-inputs]: Add package python-tzdata.
[native-inputs]: Add meson-python, python-versioneer python-matplotlib,
python-openpyxl, python-asyncio, python-pytest-localserver. Replace
python-pytest by python-pytest-next.
