Binaries for most supported platforms, including Debian Etch, SuSE 10.2,
Ubuntu Edgy, OS X, and Windows are available at http://download.qgis.org. The
source code is also available, as is a Gentoo ebuild. In the coming days we also hope to have a binary bundle that will run on any Linux platform.

If at all possible, please use the torrents when downloading.
