PRE-BUILD BINARY PACKAGES
Many distributions have included Fluxbox in their package-manager. Those Packages are maintained by their creators. To get more information about available binaries check the wiki-site that is dedicated to that issue.
It is a wiki, so if you are interested to support Fluxbox as a package-maintainer please feel free to add your name to that site.
In any case, please note that Fluxbox development team are not responsible for any package included in your distribution.
GIT DEVELOPMENT VERSION

Instructions that explain how to use git and build Fluxbox from the sources are in our precious wiki
