Can't install DMD 2.060 on OS X 10.6.8

[Elias Zamaria]

I am planning to try D for the first time in my life. I have a 
MacBook Pro running OS X 10.6.8 (Snow Leopard).

I went on the D downloads page and clicked on the link for the 
dmd 2.060 installer for OS X. I opened it and double clicked on 
the "DMD2.pkg" file within it. The installer came up with some 
text including a line that read "This package is intended for Mac 
OS X Leopard (10.5) only.". I tried to find a version for OS X 
10.6 but I couldn't, so I ignored the warning and clicked 
"Continue".

I clicked through the agreements and questions, and then when it 
finished, the installer gave this message:

> The installation failed. The Installer encountered an error 
> that caused the installation to fail. Contact the software 
> manufacturer for assistance.

Why did this happen? What am I supposed to do about it?
