#72501: stack not working on Mojave (macOS 10.14.6)

----------------------------+--------------------
 Tried to build stack (haskell's build tool, haskellstack) on Mojave (macOS
 10.14.6).

 The command
                        `port install stack`

 installs version 3.5.1

 However, when I try to use stack,

                        `stack build`

 stack first tries to install GHC (the Haskell compiler), and fails

 -------------------------------------------------------------------

 $ `stack build`

 {{{

 with

 Evidently, stack 3.5.1 is built for Ventura (macOS 13.0), though I am
 still on Mojave (10.14.6). Is there a workaround?
