[DRE-maint] Bug#996521: ruby-vcr: FTBFS with ruby3.0: ERROR: Test "ruby3.0" failed: cannot load such file -- webrick

[Antonio Terceiro]

Source: ruby-vcr
Version: 6.0.0+really5.0.0-1
Severity: serious
Justification: FTBFS
Tags: bookworm sid ftbfs
User: debian-ruby at lists.debian.org
Usertags: ruby3.0

Hi,

We are about to enable building against ruby3.0 on unstable. During a test
rebuild, ruby-vcr was found to fail to build in that situation.

To reproduce this locally, you need to install ruby-all-dev from experimental
on an unstable system or build chroot.

Relevant part (hopefully):

Note that webrick has been removed from the standard library. It's
already been packaged and is currently in NEW, but this package now
needs an explicit dependency on it.
