Firstly, there is change going on in the world of plugins, which I
suspect will fix this, but I haven't read up on the full details myself:

Are you using an old version of the DBIC plugin? I think that is fixed
in the most recent version.

This is a bit more tricky. With the current plugin architecture,
"schema" is not available in the DSL when you call it from another
plugin as you are doing. You can workaround this by capturing it during
plugin initialisation, as long as you load the DBIC plugin before yours.
See Plugin::Auth::Extensible::Provider::DBIC for an example:
