Checking for necessary X11 libraries before building Ghostscript
Until now, Ghostscript was using some host system's X11 libraries during its build (and later at run-time). We should ideally install all these necessary libraries within the template (Task #15481). But right now we are too busy. As a temporary work-around we try building a small dummy program that links with some of those libraries before attempting to built Ghostscript. If it fails, then a notice is printed with the cause and explaining a temporary solution is suggested: how to install those libraries on the system when you have root access.
