When running 

conda install -c conda-forge geant4

as it describes here:

https://anaconda.org/conda-forge/geant4

one gets an error:

PackagesNotFoundError: The following packages are not available from current channels:

  - geant4 -> geant4-data-pii==1.3



Ineed, looking at geant4 package in anaconda:

There is geant4-data-pii dependence

But there is no such package in conda

P.S. We would like to try to ship geant4 through conda for EIC package distribution
