 I am running the following script to build GHC from sources
 (ghc-8.6.2-src.tar.xz) on OpenBSD (-CURRENT):

 {{{
 #! /bin/sh
 set -e

 BUILD_DIR=/usr/local/tmp-build-ghc

 export AUTOCONF_VERSION=2.69
 export AUTOMAKE_VERSION=1.16

 if [ ! -n "$1" ]; then
     echo "ERROR: Provide path for ghc source."
     exit 1
 fi


 echo "Extracting ghc source files from ${1} to ${BUILD_DIR} ..."
 mkdir -p $BUILD_DIR

 cd $BUILD_DIR
 xzcat $1 | tar xvf -

 GHC_DIR=`ls | grep ghc`
 cd $GHC_DIR

 echo "Cleaning up OpenBSD-incompatible commands..."
 find . -type f | xargs sed -i -e 's|^ln -f -v |ln -f |'

 echo "Building GHC... "
 export CC=/usr/bin/clang

 ./boot
 ./configure --with-iconv-libraries=/usr/local/lib \
             --with-iconv-includes=/usr/local/include \
             --with-gmp-libraries=/usr/local/lib \
             --with-gmp-includes=/usr/local/include \
             --with-ffi-libraries=/usr/local/lib \
             --with-ffi-includes=/usr/local/include \
             --with-system-libffi
 gmake
 }}}

 I will file a separate bug report for the **ln** incompatibility with the
 unsupported **-v** flag.

 When compiling GHC, I get the following error:

 Any suggestions appreciated. Thanks!
