Binary rpms of modified XFree servers are currently available for Mandrake 8.2/ 9/ 9.1, Red Hat 8/ 9, SuSE 8.1 and Debian Sid. If you're running other rpm-based distributions please help me to prepare and rebuild packages, so other users can get pre-compiled binaries. Currently the binary rpm packages are not mirrored and are only available from http://varna.demon.co.uk/~svetlio/ruby-contrib.
Debian packages are also available thanks to Andreas Schuldei at http://www.schuldei.org/debian/bruby, or as apt repository "deb http://www.schuldei.org/debian/bruby ./ ".
