  What does dpkg tell when you try to install C?

  Yes, I already experienced this.

  IIRC, this is documented in policy, i.e. when you want to depend on
  a virtual package (or a provided package), you must have :

  Depends: <real package name providing B> | <virtual package name> 

  A = real package name providing B (there must be at least one)
  B = virtual package name

  I hope this helps.
