| Subject: | Required newer versions of dependent packages are not pulled in if old versions exist |
This is a critical issue IMO. I ran into it while installing the latest
DBIx::Class and having SQL::Abstract 1.51 installed. DBIx::Class
requires SQL::Abstract 1.56, and with an older version, it will fail
many tests:

At this point, the installation proceeds without upgrading SQL::Abstract.
After removing CPAN::SQLite, CPAN will pull in SQL::Abstract 1.56:

The issue is especially hurtful with Strawberry perl, which makes
CPAN::SQLite the default.
