# Optional
-----------

## Environment

Operating System: FreeBSD 14.0
Python version if appropriate: 3.11

## Reproduction Steps
Regular build.

## Log output if appropriate
https://pkg-status.freebsd.org/beefy22/data/140amd64-default/28444692ea26/logs/py311-opentimelineio-0.16.0.log

Start by reproducing the regular build on FreeBSD 14.0 with Python 3.11 and review the linked build log. Inspect src/deps/pybind11/include/pybind11/detail/type_caster_base.h around line 482 and the affected binding files, including otio_imath.cpp, otio_errorStatusHandler.cpp, and otio_anyVector.cpp. Done means the OpenTimelineIO build completes without the incomplete PyFrameObject error.
