Hi @mfansler, I am new to this process and would appreciate some feedback. I built this using the approach in [r-conda-skeleton-helpers](https://github.com/bgruening/conda_r_skeleton_helper. I am trying to understand why the win build is failing and the degree to which this is a problem. Presumably this is less of a problem if the crossdes package is noarch but I don't know where to find that. Any advice helpful

Thanks for submitting this! ❤️

RE: failed win-64 build. This is a known issue, and possibly has something to do with the intermediate state of the MSYS2/M2W64 stack for Windows. Fortunately, it only seems to arise with noarch builds, and - as you correctly observe - we don't need them anyway since in practice Conda Forge does noarch builds on linux-64.

Amazing, thanks for the info and the fast response!
