Running LDC on a recent MacOS

[Dmitry Olshansky]

So I've got my hands on one of 'em MacPros. Great machine, nice 
build quality.

Next order of business is to run D on the box, so I've downloaded 
universal binaries off ldc's release page. When I try to run any 
of the binaries nasty message box comes out to tell me it doesn't 
recognise the author of the binary. Any attempt to bypass the 
message turns to failure for me.

Any advice from MacOS users?
