2.2.17 auto-install?

Um, so, I went to update my GIMP after being largely offline for a year. The latest is 2.2.17, but all the packages I'm finding seem to be source installations? In the INSTALL file, it says to 'contact your distributor' or somesuch.... where can I find a package that has an installer rather than a zip with a bunch of confusing libraries?

Thanks again, guys!
