For some reason I need to use protobuf 2.4.1 in my project on OS X El Capitan. However homebrew has removed protobuf241 from its formula. I install it according @kksensei's answer manually and have to fix some error during the process.

During the make process, I get 3 error like following:

google/protobuf/message.cc:130:60: error: implicit instantiation of undefined template 'std::__1::basic_istream >'

  return ParseFromZeroCopyStream(&zero_copy_input) && input->eof();

(Sorry, I dont know how to attach code when the code contains '`' )

If you get the same error, please edit src/google/protobuf/message.cc, add #include at the top of the file and do $ make again and should get no errors. After that do $ sudo make install. When install finished $protoc --version should display the correct result.
