Feature Request: Support for PICRUSt2 Installation on Apple Silicon (M2)

[borexino]

I’ve noticed there is currently no formula available for installing PICRUSt2.

In #1961, I detailed the challenges of installing a required component (epa-ng) for PICRUSt2 on ARM64 devices, specifically on a MacBook Pro M2 using Sequoia.

Would it be possible to create a dedicated formula for PICRUSt2 to address this issue?

This enhancement would greatly simplify installation for Apple Silicon users and potentially resolve issue #1961.

Thank you for your consideration!

epa-ng tool depends on genesis, cereal, pll-modules, and libpll-2. Over the past week, I attempted to build and install these dependencies on an Apple Silicon (ARM64) platform, addressing them one by one. While the build and installation processes were successful, the numerical tests for pll-modules and libpll-2 failed to pass correctly. This indicates that their results cannot be guaranteed.
I have no plans to release these formulae as I don't want to cause the confusion. If you wish, please request ARM64 support on the GitHub repositories of epa-ng, libpll (and pll-modules), and genesis (cereal can be built on ARM64). if it is implemented, I will be able to provide support here.

Hi @YoshitakaMo,

Thank you for your explanation and your efforts to build and test these dependencies on ARM64 platforms. I have followed your suggestion and submitted requests for ARM64 support to the GitHub repositories of epa-ng, libpll and pll-modules
However, if I understand correctly, the GENESIS package you referred to may already have a specific ARM64 binary available through Bioconductor. This could simplify compatibility for that dependency.

Thanks
