namespace mismatch: bulk bindings not found in registry for module

While running the Racket code within Lakeroad, or when building the Docker image, if you see an error like:

#34 91.75 namespace mismatch: bulk bindings not found in registry for module: #<resolved-module-path:"/root/lakeroad/bin/utils.rkt">

it is likely due to the fact that errortrace has slipped in to a #lang line in the code somewhere. That is, the first line of any Racket file in Lakeroad should be something like #lang racket/base and not #lang errortrace racket/base.
