I've just installed the latest dmd version (on ubuntu 64bit) and I get this:

$ dmd --version
DMD64 D Compiler v2.076.0-dirty

What does 'dirty' mean?

Just ignore it. This was a bug that accidentally slipped in as the way the version is generated has been changed recently. It has already been fixed: https://github.com/dlang/installer/pull/250

For more details, see the PR or the linked issue.

Personally, I think that how the version number is handled needs further tweaking, as the recent changes have screwed up __VERSION__ for master:
