It might be in our interest to base our builds based on conda-forge. Here is what comes to my mind to enable the migration:

• Cache conda-forge recent (and needed) packages from linux-64 and osx-64 and osx-arm64 builds
• update libblitz-feedstock to match ours
• Fix and merge https://github.com/conda-forge/vlfeat-feedstock/pull/9
• Submit zc.buildout to conda-forge
• Submit zc.recipe.egg to conda-forge
• We need to use conda-forge docker image(s), their compilers, and mac requirements
• Start building bob/bob.devtools> based on conda-forge
• Start building bob/conda> based on conda-forge (only keeping bob-devel and beat-devel)
• Start building bob packages based on conda-forge
