Good question:

For me, macports is the one.

Why? I'll bypass a lot of stuff and cut right to the chase:

The party is over with regard to malware, trojans and the like. Paging through the last security update, there were some vulns that were from the summer although the cure only came last week. Redownload the developer tools, recompile your macports install, and you have a functioning toolchain that is not dependent on Cupertino, since the Dev Tools from your install disk will serve. Who uses an old version of Openssh? Now it does take some care and feeding, like running port selfupdate every day, and the big tip is to check

port variants 

so if you have a python dependency, you can run

port install python +no_tkinter 

and avoid the agonizingly long Tk install, which would be most unwelcome on a Quartz architecture anyway.

With this, you can freely run software update and not have your stuff break, since it does not depend on anything but the compiler from apple. I've used it for a long time, and although I tried some others, namely Homebrew, I think that depending on apples versions means inheriting their security flaws. Remember that PDF hole on the iphone? I deploy on Linux anyway, so for me, macports tree is the 'office' and my budding MacOS dev career is 'home'

Just an opinion, but the separate tree for all the code is a big plus for me.

Unfortunately, there appears to be no way to create a favicon via the gui elements of iWeb. However, you are able to pretty simply add the html to the published version of your site.

I recommend following this guide from All About iWeb. It walks you through how to first create the favicon using one of a variety of free online tools and then informs you where it needs be stored in your site's structure as well as the necessary html you need to add to your pages.
