I noticed that when installing dask-mpi by itself, it does not come
with any dependencies, contrary to what setup.py hints at.

On a barebones cluster, I got this trying to set up a small reproducer:

-bash-4.2$ python3 -mvenv foobar; . ./foobar/bin/activate; pip install dask-mpi
Collecting dask-mpi
  Using cached dask_mpi-2022.4.0-py3-none-any.whl (11 kB)
Installing collected packages: dask-mpi
Successfully installed dask-mpi-2022.4.0
(foobar) -bash-4.2$ pip list
Package    Version
---------- --------
dask-mpi   2022.4.0
pip        22.0.4
setuptools 47.1.0

It seems that the code that actually specifies the dependencies has been
commented out for a while. This PR reactivates it.

Tested with python -mbuild -n (no build isolation due to the YAML
dependency for setup.py) and looking at the METADATA file of the
resulting wheel.

@kmpaul any idea why these are commented out? It looks like @andersy005 made the change some time ago.

thank you for working on this fix, @matz-e

@kmpaul any idea why these are commented out? It looks like @andersy005 made the change some time ago.

It appears that I commented out these lines as a temporary solution in this pull request, but I completely forgot to submit a follow-up pull request to address the issue I raised.
