Running Metfrag as Container fails

[meowcat]

The Metfrag tool runs fine when running with a local executor. However, when I use a Docker executor, Metfrag fails. The reason seems to be that it requires Python which is not included in quay.io/biocontainers/metfrag:2.4.5.

I imagine the fix would be to add a Python requirement in <requirements> and Galaxy would make a "mulled container", at least that's what I hope...

Not even using the dynamic runner docker_dispatch to send non-container tools to local helps, since Metfrag believes it can run on docker.

It can be "fixed" by adding a resubmit to local on any error in the job_conf.yml
