Hi,

We are about to start the ruby3.1 transition in unstable. While trying to
rebuild ruby-kyotocabinet with ruby3.1 enabled, the build failed.

Relevant part of the build log (hopefully):

The full build log is available from:
https://people.debian.org/~terceiro/ruby3.1/ruby-kyotocabinet_1.34-0.1+rebuild1658134192_amd64.log

To reproduce this, you need to install ruby-all-dev >= 1:3.0+2 (in experimental).
If you fail to reproduce, please provide a build log and diff it with mine
so that we can identify if something relevant changed in the meantime.
