what is considered a devel version of nim?
The jester readme says `# Note: Starting with Jester 0.3.0, a devel version of Nim is required.` What is considered a devel version of nim? Is having a late enough version of nim enough, or does num **have** to be built and run from from github? This sounds like an inconvenient limitation?

I am running `Nim Compiler Version 0.20.2 [MacOSX: amd64]` which was installed on Mac using `brew`. The main hello world example builds and runs, but I get 404 visiting `http://0.0.0.0:5000`.
