Why do I get a different error?:

.../linux/bin64/../../src/phobos/std/datetime.d(106): Error: module std.datetime from file .../linux/bin64/../../src/phobos/std/datetime.d conflicts with package name datetime

That implies you have a borked install of dmd. How did you install it? You didn't do something like unzip a newer release on top of an older one did you? If you're using the zip file to install dmd, you have to blow away the previous install before copying over the new one, or you're screwed anytime that files get removed or moved around. I wouldn't expect that particular error if dmd were installed via the package manager.

In 2.076.0, std.datetime was split into a package. So, if you somehow ended up with both the old files and new ones, there's a conflict. With 2.076.0, it could result in linker problems, because the compiler didn't properly detected it, but it was since fixed so that the compiler sees that you have both module and a package of the same name and gives an error.
