I'm not sure how to do this and I can't test it. Could you suggest a fix?

I guess we would need some #ifdef around the following code in GlobalParameters.cpp:

  std::string home_directory(std::getenv("HOME"));
  parameter_files.push_back(home_directory + "/.dolfin/parameters.xml.gz");
  parameter_files.push_back(home_directory + "/.dolfin/parameters.xml");
