I have dub 0.9.13-0 installed from the APT_Repository for D, with libevent-dev 2.0.16-stable-1 and libssl 1.0.1-4ubuntu5.9. My operating system is ElementaryOS Beta 2, which is based on Ubuntu. I'm getting this error when I try to compile the basic example by running dub -v in the project directory.
