Comment (by rseichter):

 Quoting my own post (https://lists.macports.org/pipermail/macports-
 dev/2019-April/040509.html) because unfortunately there was no response:
 {{{
 I wanted to take a shot at updating the Pandoc port from version 1.12 to
 2.7.1, but the GHC prerequisite build fails.

   :info:build deriveConstants: fd:31: hClose: invalid argument (Bad file
 descriptor)
   :info:build make[1]: *** [includes/dist-
 derivedconstants/header/DerivedConstants.h] Error 1

 I found https://trac.macports.org/ticket/48899 but I am unsure if I
 should add the build log file there or if a new ticket would be better?
 I am also wondering about the chances of actually finding somebody
 willing to work on Haskell, seeing that the existing ticket was filed
 four years ago? Personally, I don't know enough about GHC.

 P.S.: I know there is a Pandoc installer for macOS available, but it
 looks like conversion to PDF does not work out of the box.
 }}}

 I have now attached the GHC build log to this ticket.
