"fun" fact? this only fails inside Puppet. Native Ruby from Debian installs it fine. Puppet's Ruby does not. 👀

This seems to be caused by the way Ruby is build by Vanagon to be bundled in AIO packages: at build time, mkdir(1) is found as /usr/bin/mkdir for (bad?) reasons, and this path is saved in rbconfig.rb (part of Ruby) that is used to generate Makefiles when building native gems.
