Ok, some reproduction steps. Starting from the `pyarrow-13.0.0.tar.gz`:
```sh
~/Downloads/pyarrow-13.0.0 ❯ PYARROW_WITH_PARQUET=1 PYARROW_WITH_FLIGHT=1
python -m build
...
Successfully built pyarrow-13.0.0.tar.gz and
pyarrow-13.0.0-cp312-cp312-macosx_14_0_arm64.whl
```
```sh
~/Downloads/pyarrow-13.0.0 ❯ python -m installer
dist/pyarrow-13.0.0-cp312-cp312-macosx_14_0_arm64.whl
```
At this point, it doesn't work:
```sh
~/Downloads/pyarrow-13.0.0 ❯ python -c "import pyarrow"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/dylan/Downloads/pyarrow-13.0.0/pyarrow/__init__.py", line 65,
in <module>
import pyarrow.lib as _lib
ModuleNotFoundError: No module named 'pyarrow.lib'
```
Now, I move into the `site-packages` directory and import locally:
```sh
.../lib/python3.12/site-packages ❯ python -c "import pyarrow;
print(pyarrow.__version__)"
13.0.0
```
It works! And now returning to an arbitrary directory, it also works.
```sh
~ ❯ python -c "import pyarrow; print(pyarrow.__version__)"
13.0.0
```
It seems like performing the import locally in `site-packages` "fixes"
something. It doesn't seem like anything has been updated anywhere (e.g. in
`__pycache__`) from the timestamps however. The timestamps all match the
original installation time.
