Currently you can see this in the logs when starting the docker container. Filed here in core since this seems to be related to those binaries:

While looking for a fix for this issue, I fixed several minor bugs:
#67
#68
In the process, this "CFile is not defined" was gone for me. I can't say exactly which change led to the fix.
