I suspect your issue is caused by botan library on which vibe-d 
depends:
http://code.dlang.org/packages/botan
It says it needs MS linker on Windows and so most probably 
depends on MSVC runtime.
Usually when you build something with DMD without -m64 or 
-m32mscoff it makes a binary without such dependencies, it uses 
its own C library (snn.lib) statically linked.
