[racket-dev] Building docs in v5.0.99.900

I'm seeing this error when installing a .plt file using the current 
release candidate:

...
raco setup: --- creating launchers ---

link: reference (phase 0) to a variable in module "/Applications/Racket 
v5.0.99.900/collects/scribble/private/manual-proc.rkt" that is 
uninitialized (phase level 0); reference appears in module: 
"/Applications/Racket
