If by current you mean git-head, only git-head versions of DMD are
compatible with git-head versions of druntime and phobos. Meaning it's
normal that an e.g. 2.066 compiler will not build a Phobos commit
after the commit tagged v2.066 (it may work for a while, but things
usually break quick enough either through things like mangling changes
or accepts-invalid bug fixes, to name a few).
