Weird, clearly shows up as `XZ compressed data` on my Linux box and also unpacks with `tar -Jtf dmd.2.074.1.osx.tar.xz`.
Can't really test this as my OSX machine still is on 10.8 and doesn't have built-in tar.xz support (only added CLI support via http://macpkg.sourceforge.net/).
Could you please retest and check whether that is still an issue with current downloads, and whether 2.074.1 reproducibly fails?
That tar archives are packed and compressed on the host machine, so there might have been tar/xz updates.

Can someone please retest this?

That archive decompresses fine for me when I double click on it in a Finder window on a 64-bit mac. Archive Utility version 10.11 (101.5.1).

Closing as WORKSFORME for now, but please reopen if someone can reproduce.
