Version 5.2.1 is old enough that I'm starting to forget, but I think
there may still have been a lingering places bug that could cause `raco
setup' to get stuck. I also remember vaguely that the problem showed up
more often on 64-bit Linux, but that could be wishful thinking.

Does it help to run `raco setup -j 1'?
