`FormatTime string_view` not found when importing vegafusion (this used to work)

[jowens]

Entirely possible this is not a vegafusion issue, and I don't know what library upgrade caused it, for which I apologize profusely. Any pointer would be appreciated.

Hi @jowens, I think there is some version mismatch happening between different arrow shared libraries. I'm not familiar with installing pyarrow through MacPorts, but the version 1.3.0 of py312-arrow not matching version 13.0.0 of py312-pyarrow might be an issue.

If it's a possibility for you, I'd recommend uninstalling all of the (py)arrow packages from MacPorts and then install just the pyarrow package using pip, as this bundles the Python and native arrow dependencies in one package.

[jowens]

Understood. This helps me track down the mismatch! Thank you. I will report back when I identify it in hopes of helping others.

A rebuild of abseil and all its dependencies solved this problem (https://trac.macports.org/ticket/69932). Thanks @jonmmease!
