It looks like this was built with -package-name syb-0.2.0.0, but it
should be built with -package-name syb. There should be
ghc-options: -package-name syb
in the .cabal file to make this happen.

Yes, that works, thanks. I thought this problem was caused by having the syb package unversioned in the GHC repo, and I also thought that that had changed, but now I see that the flag -package-name syb is still there. Would you know if this necessary for some reason?

Thanks,
Pedro
