The pinning mechanism doesn't play well with our planned git dependencies however, in fact it's similar to what we have now with devmode vcs checkouts :)

Yes, but can't we achieve this by determining haxelib.exe folder somehow and using that instead of HAXEPATH?

I think we can try using `Sys.executablePath()` on Windows, since we're always dealing with `haxelib.exe` there. Unless we want to change it to some `haxelib.cmd` batch file that does `haxe...

note that it would be great to also be able to specify commit number/branch/tag (like npm does I think)
