          #{python.prefix}

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


    If this is your first install, create a database with:
      initdb #{var}/postgres -E utf8


    To migrate existing data from a previous major version (pre-9.2) of PostgreSQL, see:
      http://www.postgresql.org/docs/9.2/static/upgrading.html


    Some machines may require provisioning of shared memory:
      http://www.postgresql.org/docs/9.2/static/kernel-resources.html#SYSVIPC

  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.
