download_prerequisites does install from source (integrated into the gcc build). It saves a lot of annoyance over hunting for the right versions. I've used those downloads separately to configure and make installations in /usr as well.As it says there, the simplest way to install them is from your OS package management system. The next best option is to use the contrib/download_prerequisites script in the GCC source. Either of those options should ensure everything just works. The last resort, which usually causes problems for people who don't know what they're doing, is to install the support library from source.
