I think you need to install the ogg libraries. Derelict, which
Dgame uses, only provides bindings to the C/C++ libraries. You
still need to get the those libraries for things to work.
Sorry I cannot help more. On linux it's just a matter of using
the pkg manager (apt, pacman, yum etc.) On MAC I have not idea.
I can confirm Dgame 0.4.1 is now working on Linux (Debian
x86_64) after I did a dub upgrade.
That is nice to hear. It works for me on Windows 8.1. Someone
with a Mac here?
