Compiling Fails due to sklearn/metrics/pairwise.py

### Describe the bug

_This may be a duplicate of [29754](https://github.com/scikit-learn/scikit-learn/issues/29754)._ 

Having merged from upstream, the imports in `sklearn/metrics/pairwise.py` do not compile. 

I am getting error:
"sklearn/metrics/_dist_metrics.pyx", line 1, in init sklearn.metrics._dist_metrics"

I have tried rebuilding my conda environment and sklearn.


### Steps/Code to Reproduce

$ python -m sklearn.kernel_approximation

### Expected Results

not an error

### Actual Results

```python

COMMENT:
This is not related to https://github.com/scikit-learn/scikit-learn/issues/29754. The latter issue is related the wheels building and fail for Windows while you are under MacOS.

The error that you witness is related to https://github.com/numpy/numpy/issues/26710. I'm a bit confused why you get it with the development version. Normally, the error is triggered when you have NumPy 2.0+ with an older version of scikit-learn that is not compatible with NumPy 2.0+.

Could you retry to clean and rebuild from source with shown dependencies.
