Hi,

We are about to start the ruby3.1 transition in unstable. While trying to
rebuild ruby-uglifier 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/ruby3.1/17/ruby-uglifier/ruby-uglifier_4.2.0+dfsg-1+rebuild1663008282_amd64-2022-09-12T18:44:43Z.build

To reproduce this, you need to install ruby-all-dev >= 1:3.0+2. Depending on
when you try this, it might mean installing ruby-all-dev from experimental, or
if the transition has already started, a normal build on unstable will be
enough.  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.
