Another thing is to check which versions of Perl the `perl` command corresponds to and whether that matches the version the module is installed for. p5-dbd-mysql currently implies installing p5.28-dbd-mysql, so it should work for perl5.28. If still using perl5.26, then p5.26-dbd-mysql would need to be manually requested if not already present.
