in reply to DBD-mysql stubbornly refusing to install

DBD::mysql has problems with clients version 8+. Could you try installing DBD::MariaDB instead? It's a fork of the former module that fixes compatibility with the recent clients among other things.

    Thanks for that insight which explains a lot. I would be very happy to try DBD::MariaDB (of which I was unaware until you wrote so thanks again) but I'm not sure if it's compatible with Rose::DB::Object or indeed how to configure Rose to use it. Does anyone know?
      I haven't used Rose::DB ever, but from the documentation it seems you'd have to copy Rose::DB::MySQL to Rose::DB::MariaDB and use the driver_class method to enable it. If you decide to go that path, don't forget to post the traps and discoveries you make :-)

      Update: See also Bug #125886.

        OK, well it seems that Rose isn't compatible with Rose::DB::MariaDB. I could have a go at tinkering with it but the need has gone away as I've found a workaround for my problem with Active State Perl which has a version of DBD::mysql that does work. (I don't see how they've managed to do that actually - if DBD::mysql is not compatible with V8 Mysql, how have AS got it working?). Thanks for the advice, though; saved me wasting more time and hopefully useful for others in a similar situation, too.
