Can't install DMD 2.060 on OS X 10.6.8

[Elias Zamaria]

How can I get permission to run "sudo". I thought that "sudo" was 
the command required to get permission to run other things. Is 
there a catch-22? In any case, why am I having this problem, and 
why don't I see any hint that anyone else is experiencing it?
