If you use ARM devices, it might be worth pointing out that Dave Cheney has unofficial tarballs of _older_ versions here:

No 1.5 (yet), but if, like me, you do ARM stuff, you might want to bookmark this.

And of course the cross-compiler works, but still.

(edit: moved mention of ARM to first line)
