Install libmemcached with brew in preview (build 13A558) version of OSX Mavericks with XCode 5 Developer Preview 6

libmemcached.rb

require 'formula'

class Libmemcached < Formula
  homepage 'http://libmemcached.org'
  url 'https://launchpad.net/libmemcached/1.0/1.0.17/+download/libmemcached-1.0.17.tar.gz'
  sha1 '1023bc8c738b1f5b8ea2cd16d709ec6b47c3efa8'

  depends_on 'memcached'

  def install
    ENV.append_to_cflags "-undefined dynamic_lookup" if MacOS.version <= :leopard

    if MacOS.version > :mountain_lion
      ENV.append 'CXXFLAGS', "-I#{MacOS.sdk_path}/usr/include/c++/4.2.1"
      ENV.append 'LIBS', "#{MacOS.sdk_path}/usr/lib/libstdc++.dylib"
    end

    system "./configure", "--prefix=#{prefix}"
    system "make install"
  end
end

Until the problem is fixed permanently (by whatever party - I reported to all of them), you can manually modify libmemcached brew formula by running

brew edit libmemcached

More details about the problem and issues opened are in Homebrew: Homebrew/legacy-homebrew#20635 and Libmemcached: https://bugs.launchpad.net/libmemcached/+bug/1216521

Thanks so much for this! I can't believe you still get the "<tr1/cinttypes>" error on Mavericks when installing libmemcached via brew.
