Comment:

I'm building a package depending on openmpi. I pinned the run dependency version to 4.1.6 (which is on conda-forge). However when installing the package it sometimes resolve to the external build. As a consequence when I install the package it doesn't work because the external build doesn't install any binaries (as expected).

Any idea on why this happens?

I might want to pin to openmpi=4.1.6=h* but that would defeat the purpose of having external builds.

Thanks in advance
