FreeBSD 10 switched completely to clang and libc++.so, but we build the binary release with FreeBSD 8.4 that still uses g++ and libstdc++.so. Thus the dmd binaries won't run. Shared object "libstdc++.so.6" not found, required by "dmd" A temporary workaround is to install the lang/gcc package. pkg install lang/gcc http://blog.khmersite.net/2014/04/freebsd-10-shared-object-libstdc-so-6-not-found/ https://wiki.freebsd.org/NewC++Stack
FWIW with 2.080, DMD will only officially support FreeBSD 11 as the older build hosts have been dropped.
