Mac OS installer

[Adam D. Ruppe]

I was recently involved in a stack overflow question about mac os:

http://stackoverflow.com/questions/12832241/cant-install-dmd-2-060-on-os-x-10-6-8/12897850

I gave my usual answer of "just use the zip" which solved the 
problem there, but perhaps there's something we can do to improve 
the installer so people who do use it can have an easier time.

I don't know anything about the Mac though, so there's nothing 
more I can do except punt it to someone else... so here I am.
