The build fails immediately. Downgrading setuptools to version 76 lets it build normally
Confirming the issue and workaround. Also was downgraded to caffe2-2.5.1-r10.

I have same problem
It seems the version affected is only setuptools-77.0.3 77.0.1 or 78.0.2 are not affected
I think the best fix is to yank 77.0.3. https://github.com/pypa/setuptools/commit/d2cf96a3437b830499c88865eb6546feeff198d8 reverts the change if you do want to patch 77.0.3
