You need to put the exe in your PATH and rename it yourself, but it recognizes *dmd-* (or *ldc2-* or *gdc-*) all the same so you can specifiy them.
I was doing that in early versions of my android thing, i made a program "android-ldc" and then did "dub build --compiler=android-ldc" and it all worked.
S o you can do that with versions too.
