We are pulling out from using this package, which is unfortunate.
@grisha, it would be really useful if you could get this working on a modern system.
During the build there were several 'deprecated' notifications.

Yep, it's a shame all right. You should reconsider.

I would like to help with your issues, unfortunately I am not familiar with compile errors. I can tell you that I compile modpython form git often on debian 11 (amd64) and have had no problems.

./configure
make
checkinstall -D --install=no

I don't see any errors. That gives me a deb I can install on both of my machines. Works great.
