    # On 64-bit systems, we need to look for a 32-bit Framework Python.

          #{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

    end

  def caveats
    s = <<-EOS.undent
      If builds of PostgreSQL 9 are failing and you have version 8.x installed,
      you may need to remove the previous version first. See:
        https://github.com/mxcl/homebrew/issues/issue/2510

      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/9.0/static/install-procedure.html

      If this is your first install, create a database with:
        initdb #{var}/postgres9

      Some machines may require provisioning of shared memory:
        http://www.postgresql.org/docs/current/static/kernel-resources.html#SYSVIPC
    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.
