Ah, I see. Now that I know that, I can duplicate the problem more
easily: just having Plot's "draw.rkt" open in another tab gives me a
link error. As soon as I close that tab, DrRacket uses the .zo files
compiled by raco setup, and plotting works again.
Another workaround (besides closing a tab) is to choose "No debugging or
profiling" from the language dialog. Apparently, that makes the .zo
files DrRacket builds compatible with the output of raco setup. But I
still have to wait for it to recompile everything the first time.
I think the current behavior would be fine with a small tweak. Is it
possible for DrRacket to determine whether each .zo file in the
"compiled" directory is up-to-date, and use those that are? Then I could
either have DrRacket's on-demand compiler build Plot, or use raco setup.
(The former would be much easier if the "-c" flag could clean just one
collection or package, though.)

Yes: as an experiment we decided to treat files that are open
differently than other files for the purposes of recompiling them.
Looks like that's probably a bad design decision. But it may just be a
bug too, since I thought it was re-compiling more, not less, when you
have the file open.

Try this:
- open the menu "Language" in DrRacket
- choose the menu item "Choose language..."
- click the button "Show details"
