It's not collections that need to be specified, just packages. Here
are the missing dependencies for "markdown", for example, as printed
out by `raco setup`:

raco setup: undeclared dependency detected
raco setup:   for package: "markdown"
raco setup:   on packages:
raco setup:    "base"
raco setup:    "sandbox-lib"
raco setup:    "scribble-lib"
raco setup:    "srfi-lite-lib"
raco setup:   on packages for build:
raco setup:    "at-exp-lib"
raco setup:    "html-lib"
raco setup:    "rackunit-lib"
raco setup:    "redex-lib"

For "rackjure", it's:

raco setup: undeclared dependency detected
raco setup:   for package: "rackjure"
raco setup:   on package:
raco setup:    "base"
raco setup:   on package for build:
raco setup:    "rackunit-lib"

Fortunately, `raco setup` spits out exactly the needed info.

There's lots of info that the raco tools `check-requires`,
`show-deps`, and `show-dependencies` provide.

The middle of those is https://github.com/samth/find-pkg-deps, the
other two are provided by the macro debugger.

That sounds awesome.
