Issue with openmpi build

[sblauth]

I have encountered an issue with openmpi when building my package cashocs for conda-forge. The package can either use the mpich or openmpi implementation for parallelism, but the conda-forge build fails, when openmpi is used (see https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=564717&view=results)
The error message is

--------------------------------------------------------------------------
The value of the MCA parameter "plm_rsh_agent" was set to a path
that could not be found:

  plm_rsh_agent: ssh : rsh

Please either unset the parameter, or check that the path is correct
--------------------------------------------------------------------------

Either specifying mpich as dependency (https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=564951&view=results) or adding openssh as dependency (see https://dev.azure.com/conda-forge/feedstock-builds/_build/results?buildId=564963&view=results) works. To me, it seems that ssh is missing in the docker container for building the recipe. Is there any way to resolve this?

Thanks and best regards,
Sebastian

This issue is in the wrong place. Please post it to the feedstock of the package. I am closing it for now.
