If not, I am amazed that someone managed to build a binary on armv7l that works on armv6l.
I was pretty sure the devs didn't use any armv7 specific instructions so it should work - just tested the binary on a pi model b and it works fine.
Regarding the static build it would be the easiest way to run dmd on most arm boxes - even kodi can run a node despite it doesn't let you install libraries.
Oh yeah! I remember now - building for armv7l or armv6l is the same, they're just there for the sake of dispelling confusion. (I'm the one that made the commits to remove the SSE2 requirements, but it's been a while.)
As for static builds, I believe that some standard libraries are linked, but that linking other stuff (like BDB) is highly discouraged. It would also tie desktop integration (transaction popups and, I believe, the taskbar icon) to a specific window manager. In the case of the RPi, I guess that would be fine for most normal RPi users, but it could get hairy if someone using a STB wanted to use the binaries (those distributions are all over the place).
