Generating Linux Makefile with Introjucer

I downloaded juce for Linux (the latest via git), built it and built IntroJucer - no problems. I generated a project with Introjucer and do not see a tab for Linux Makfile - just iOS, Mac OS X, and VS. Also, open as Makefile doesn’t seem to do anything. What am I missing? Can Introjucer generate Linux Makefiles for projects?

Nevermind - stupid user error. :?
