Huh, odd.

I downloaded 
https://www.cs.utah.edu/plt/snapshots/current/installers/racket-7.5.0.6-x86_64-macosx.dmg
and I was running a bunch of local-built networking code.  I had to do
some faffing about to get PLTCOLLECTS and such set up properly, so it
may be a purely my-problem problem.

One thing I did find odd:

$ which raco
/Applications/snapshot_Racket_v7.5.0.6/bin/raco

$ raco pkg install handy
/Applications/snapshot_Racket_v7.5.0.6/bin/raco: Unrecognized command: pkg

Usage: raco <command> <option> ... <arg> ...

Frequently used commands:
  docs                 search and view documentation
  make                 compile source to bytecode
  planet               manage Planet package installations
  exe                  create executable
  test                 run tests associated with files/directories

A command can be specified by an unambiguous prefix.

This is probably a mistake on my end, and it may fix itself once the
recompile finishes (maybe?) but why would the pkg command be missing?
