What were you trying to do (and why)?

brew unbottled --tag arm64_sequoia --dependents -v vtk

What happened (include all command output)?

running above command with homebrew on ubuntu 22.04 with homebrew setup in the default prefix gives me the below stack trace.

running that same command on macos 15 m1 aka arm64 box gives me the below output,

==> Populating dependency tree...
==> :arm64_sequoia bottle status
vtk: doesn't support this macOS

What did you expect to happen?

i would expect the command list the dependencies of vtk that are not bottled.

Step-by-step reproduction instructions (by running brew commands)

run above mentioned commands,
