Comment 10 for bug 173890

Brandon's 64-bit flashplugin-nonfree package has still not started building:

Information on Brandon's package is available here (you can download the source packages from here):

If you want to download a binary package, do so here (only 32-bit has been built):

64-bit users currently must compile their own packages using the source packages available at the information on the package (second link).
