Compilation failure w/ GHC 7.8.4 and lens-4.8 - there seems to be a missing symbol #72

I've got a really strange failure building linear when lens is loaded via TH. Am I even at the right issue tracker here, or is something missing on the lens-side?

This is likely a problem with your local installation. You might need to reinstall some things.

That did it, thank you. I was hesitant at first to throw away and rebuild all of ghc's packages, but alas... Sry for the noise, I'll close the issue.

Just glad it wasn't something we did, because I had no idea how to fix it. =)
