You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: guile@2.rb
    path of file: ./repos/homebrew-core/Formula/g
    
    the code of the file until where you have to start completion: class GuileAT2 < Formula
  desc "GNU Ubi
    
  def install
    # Avoid superenv shim
    inreplace "meta/guile-config.in", "@PKG_CONFIG@", Formula["pkg-config"].opt_bin/"pkg-config"

    system "./configure", "--disable-dependency-tracking",
                          "--prefix=#{prefix}",
                          "--with-libreadline-prefix=#{Formula["readline"].opt_prefix}",
                          "--with-libgmp-prefix=#{Formula["gmp"].opt_prefix}"
    system "make", "install"

    # A really messed up workaround required on macOS --mkhl
    lib.glob("*.dylib") do |dylib|
      lib.install_symlink dylib.basename => "#{dylib.basename(".dylib")}.so"
    end

    # This is either a solid argument for guile including options for
    # --with-xyz-prefix= for libffi and bdw-gc or a solid argument for
    # Homebrew automatically removing Cellar paths from .pc files in favour
    # of opt_prefix usage everywhere.
    inreplace lib/"pkgconfig/guile-2.2.pc" do |s|
      s.gsub! Formula["bdw-gc"].prefix.realpath, Formula["bdw-gc"].opt_prefix
