[tbeason]

This failed for me on 1.10 but works in 1.9.4

[Gnimuc]

looks like BBB's Artifacts.toml has been updated recently.

https://github.com/JuliaPackaging/BinaryBuilderBase.jl/blob/a4ef056f979007f806ff3980dc6e592f9dd4dd1b/Artifacts.toml#L2762-L2771

[Gnimuc]

replace Artifacts.toml in Clang.jl with the new one in BBB should fix the issue.
