Unfortunately, dmd has not kept porters in mind and hasn't kept 
the C++ version updated, or kept a workflow that enables easy 
bootstrapping:

You will have to build druntime and phobos for 2.067 also and 
collect it all in a different location, which you could invoke to 
bootstrap a new dmd.  You may run into issues related to D/C++ 
integration when building the latest dmd, as that hasn't been 
tested on OpenBSD, only FreeBSD.

Why do you want the latest dmd on OpenBSD?  I ask because it will 
likely require some work, though likely not a lot.
