Yes, I will have to block cython-3.0 everywhere. Nothing is ready for it in this overlay. Is there more to the error? It looks weird.

[danalytis]

Yes, I truncated the output. build log

The top error has an issue with its name upstream but the rest will require a lot of attention.

[kiwifb]

Overlay updated. All ebuilds using cython are now blocking cython-3.
