There’s an issue with the new GHC.  The “--allow-newer=…” flags no
longer work.  I can’t find any info on the Web or in any changelog.  It
seems that nobody uses “runhaskell Setup.hs …” except for us.  Right
now, I am working around this clumsily to avoid stalling (I am just
patching the Cabal files).  It ought to be fixed before everything gets
merged, though.  The best idea I’ve had so far is to update the build
system to use the “cabal” command.  Hopefully I can find something
simpler, though.

Yes!  This is a great idea.  However, maybe it’s best for a little later
(tomorrow or the next day).  Right now, I am fixing more than my
computer is building.  :)
