Wow. Great. Thanks for such quick and thorough testing.
missing seq is indeed the cause. It should be easy to work around the
lack of seq: I'll simply include this replacement function from gzip's
tests/zgrep-context:

# A limited replacement for seq: handle 1 or 2 args; increment must be 1
seq()
{
  case $# in
    1) start=1  final=$1;;
    2) start=$1 final=$2;;
    *) echo you lose 1>&2; exit 1;;
  esac
  awk 'BEGIN{for(i='$start';i<='$final';i++) print i}' < /dev/null
}
