[racket-dev] raco pkg install permission errors in 5.90?

The transcript I linked to is from a Travis CI session. It's a fairly
clean slate.

- VM with Ubuntu image and gcc tools.
- Travis git clones the repo (being tested) source
- Racke nightly build is downloaded, Racket install sh script is run.
- raco pkg install --link <x>

Hmm. As I type this, occurs to me: What if the nightly build file
timestamps are Utah time, but the Travis server is running in a
different time zone?  Could that explain it?
