This won't solve the problem per se.

If you have :

A-v1 depends on C-v1
B-v1 depends on C-v2

You need a way to be able to tell A-v1 to use C-v2 (or B-v1 to use  C- 
v1). So that you can use both A-v1 and B-v1 toghether. In a  
distributed setting you need a way to override the dependencies and  
pray that it works and if it doesn't contact the A's developer to  
release a new version that works with C-v2.

Again this has nothing to do with the use of a vcs.
