[racket] interactive.rkt and 5.2.1: Infinite errors re path->name

I've been happily using Eli's interactive.rkt
(http://barzilay.org/misc/interactive.rkt) with 5.1.1.

I just put 5.2.1 on a Mac OS X machine.

Assume a hello.rkt that is simply

  #lang racket
  1

Then:

$ racket
Welcome to Racket 5.2.1
-> en, hello.rkt
1
dynamic-require: name is not provided: 'path->name by module:
#<resolved-module-path:"/Applications/Racket_v5.2.1/collects/setup/private/path-utils.rkt">

 === context ===
/Users/greg/.racketrc:285:0: path->name
/Users/greg/.racketrc:1092:4: namespace->prompt
/Users/greg/.racketrc:1152:4: execute131
/Applications/Racket_v5.2.1/collects/racket/private/misc.rkt:87:7

dynamic-require: name is not provided: 'path->name by module:
#<resolved-module-path:"/Applications/Racket_v5.2.1/collects/setup/private/path-utils.rkt">

 === context ===
/Users/greg/.racketrc:285:0: path->name
/Users/greg/.racketrc:1092:4: namespace->prompt
/Users/greg/.racketrc:1152:4: execute131
/Applications/Racket_v5.2.1/collects/racket/private/misc.rkt:87:7

... error repeats until you kill the racket process ...

This used to work fine with 5.1.1.

I do see that 5.1.1 defined a `path->name' in its
/Applications/Racket_v5.2.1/collects/setup/private/path-utils.rkt, and
that 5.2.1 does not. So the error seems clear. But I'm not sure how to
resolve it, and also don't understand why it's repeating infinitely.


P.S. I've simply been using interactive.rkt *as* my .racketrc -- not
loading former from latter -- in case that matters.
