Hey Devs, I'm having trouble building the head of the ghc-8.6 branch (`26a7f850d1`) on my Arch Linux machine. The essence of the error is this as follows, though the full result of make (to the point of error) is attached. ``` Configuring template-haskell-2.14.0.0... ghc-cabal: Encountered missing dependencies: ghc-boot-th ==8.6.* && ==8.7 ``` The output of configure is as follows: ``` ---------------------------------------------------------------------- Configure completed successfully.
