Ah, seems like we overlooked this, this already got fixed via:

• add EPA-ng-0.3.8 dependency to PICRUSt2-2.6.1-foss-2023a easyconfig #25163

I also don't see a reason to use foss toolchain for EPA-ng?

EPA-ng is a massively parallel tool, and it uses mpi per my config, hence foss. The merged PR for EPA-ng only uses OpenMP.

@ccoulombe Ah, thanks for the clarification

I wonder how we should proceed here then...

1. Remove EPA-ng-0.3.8-GCC-12.3.0.eb?
2. Add a versionsuffix to EPA-ng with foss (like EPA-ng-0.3.8-foss-2023a-mpi.eb), and change the dependency in PICRUSt2 accordingly?

Personally, I would keep one recipe, hence I tend towards 1.
Having one that is a superset is probably more flexible.

@ccoulombe Makes sense, let's go with 1).

Can you update your PR to remove EPA-ng-0.3.8-GCC-12.3.0.eb?
