Here is the workaround solution for the problem:
4) gclient sync Syncing projects: 2% ( 2/84) src-internal src-internal (ERROR) ---------------------------------------- [0:00:01] Started. _____ src-internal at refs/remotes/origin/master [0:00:05] Cannot fast-forward merge, attempt to rebase? (y)es / (q)uit / (s)kip :
Just push your changes to remote repo.
Seriously. Somehow gclient corectly resolves dependencies when pulling DEPS from remote.
