I could not reproduce the build failure in pigx-rnaseq. For python-dask
the build failure could be fixed by upgrading it to 2021.9.1, whose
changelog mentioned that they've deactivated a failing test when
building against Pandas >= 1.3.3. After updating dask, its dependent
packages python-distributed and python-eliot failed to build.  I've
fixed both by updating them to their latest releases and disabling
failing tests.
I've also took the oppurtunity to update the synapse package which was
the only package depending on python-eliot.

Of the remaining packages reported by `guix refresh -l python-pandas`,
I've identified the following packages with build failures:

* clipper@2.0
  sometimes fails due to nondeterministic test
  `test_get_FDR_cutoff_mean`.  The docstring of this test already says
  "Difficult to test because of random sampling" followed by a TODO.
  I've thus deactivated this test, to make it build deterministically.
* pplacer@1.1.alpha19
  already failed on master due to unbuildable ocaml4.07-re@1.10.3.
* python-scikit-rebate@0.6
  Already failed on master in test `skrebate`:
  ModuleNotFoundError: No module named 'sklearn.externals.joblib'
  (A guix refresh -u python-scikit-rebate would update it to 0.62 which
   was buildable, but this version seemed to come without any tests, so
   I'm not sure if this is the right solution.)
* orange@3.28.0
  Already failed to build on mater, because its dependency
  python-orange-canvas-core.
  I've looked into updating both to their latest version, but that
  would require updating python-pygments to >= 2.8.0 which would entail
  rebuilding 561 dependent packages.
* imp@2.13.0
  I was running out of memory while building imp, which in the end
  killed the build process. It seems that my 8GB of RAM are not
  sufficient to build imp, so I cannot tell if the update of
  python-pandas might break imp.
* tadbit@1.0.1
  depends on imp, so I couldn't build it either.

I've prepared patches for those packages that I was able to fix.

Best,
Felix
