* checking whether the namespace can be loaded with stated dependencies ... [0s] WARNING

A namespace must be able to be loaded with just the base namespace
loaded: otherwise if the namespace gets loaded by a saved object, the
session will be unable to start.

Probably some imports need to be declared in the NAMESPACE file.
