"but they tend to be temporary and easily fixed." Only if your dependencies do the same, otherwise you have a new version of something and your dependency wants something old. Especially hard when older dependencies are no longer maintained. For different environments and languages the problem might be bigger or smaller depending of the culture, strong/weak type coupling, cross compilation or runtime VMs. This is the reason we've removed all Scala dependencies and now only depend on Java dependencies.
