The latest wine from git now prompts not only for Gecko download, but also for Mono download. http://winetricks.googlecode.com/svn/trunk/src/install-gecko.sh is a handy script that I've used for a long time to avoid those pesky download prompts. It now also installs mono to avoid that second prompt. It should be probably be called wine-install-addons.sh now, maybe I'll rename it that soon. If you have a better idea for the name, let me know. (I've also deprecated the copy that was in winezeug; that one now just tells users to get it from the winetricks repo.)
