I have a problem: My closed source server yet again depends on changes in vibe-d ~master HEAD. My other open source libs like sockjs-d or gcm-d do not require this. so I would like to keep the version set to >=0.7.18 there since this is the current stable release. But, even though ~master of vibe.d would be the common denominator here dub rejects this:

There are conflicts in the dependency graph.
The dependency graph could not be filled, there are conflicts.
The following changes will be performed:
Conflict vibe-d >=~master, userWide
Issued by:
 s4server: ~master
 sockjs-d: >=0.7.18
 gcm-d: >=0.7.18
 s4db: >=0.7.18
Error executing command run: Unknown dependency: sockjs-d

what can i do ?
