    # On 64-bit systems, we need to look for a 32-bit Framework Python.
    # The configure script prefers this Python version, and if it doesn't
    # have 64-bit support then linking will fail.

    return unless framework_python.exist?

      opoo "Detected a framework Python that does not have 64-bit support in:"
      puts <<-EOS.undent
          #{framework_python}

        The configure script seems to prefer this version of Python over any others,
        so you may experience linker problems as described in:
          http://osdir.com/ml/pgsql-general/2009-09/msg00160.html

        To fix this issue, you may need to either delete the version of Python
        shown above, or move it out of the way before brewing PostgreSQL.

        Note that a framework Python in /Library/Frameworks/Python.framework is
        the "MacPython" verison, and not the system-provided version which is in:
          /System/Library/Frameworks/Python.framework
      EOS
    end
  end

  def caveats
    s = <<-EOS.undent
      To build plpython against a specific Python, set PYTHON prior to brewing:
        PYTHON=/usr/local/bin/python brew install postgresql
      See:
        http://www.postgresql.org/docs/8.4/static/install-procedure.html


      If this is your first install, create a database with:
          initdb #{var}/postgres
    EOS

    s << gem_caveats if MacOS.prefer_64_bit?
    return s
  end

  def gem_caveats; <<-EOS.undent
    When installing the postgres gem, including ARCHFLAGS is recommended:
      ARCHFLAGS="-arch x86_64" gem install pg

    To install gems without sudo, see the Homebrew wiki.
