[racket-dev] sporadic failure when building PLaneT docs

I'm seeing the following error message when I'm compiling Whalesong:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
require: unknown module: 'program
raco setup: error: during Building docs for
/home/dyoo/.racket/planet/300/5.1.3/cache/dyoo/closure-compile.plt/1/2/manual.scrbl
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;


Wait, that's odd!  I thought that my closure-compile package compiled
cleanly.  I tested this!



I removed the closure-compile.plt package, and then tried reinstalling
that package directly.  To my dismay: I couldn't reproduce the error:
the transcript below shows that I don't get a error about "unknown
module":

Odd.  I removed all the packages from my system, and tried setting up
Whalesong again.  I created a development link to Whalesong, and then
started the installation procedure:

I'm confused now, because it does appear that the compilation error is
context-sensitive.  It appears to show up if I'm building a collection
that requires my closure-compile.plt PLaneT package.

I've been staring at the source to closure-compile.plt's manual.scrbl
file, but I don't see anything there that should care about the
compilation context.
