btw, yum install fluxbox may work. I'm not sure if it's in the repos that are included on the tzulo fedora distributions.
pretty sure I ended up compiling it from source. this should work:
after the ./configure or make step, it may spit out an error, saying that you require a certain library or program. copy/paste here and we'll work it out for you. if everything installed correctly, start a vnc session and type fluxbox and it should start for you.
tar -jxvf fluxbox-1.1.1.tar.bz2
