 The conflicts statement seems not to work if there is no dependencies in a
 Portfile. I will explain with an example.

 darts and darts-clone ports conflict with each other. If darts-clone
 already exists, darts cannot be installed as expected. On the other hand,
 the installation procedure of darts-clone will start even if darts exists.
 One difference between the two ports is that darts-clone has no
 dependencies although darts has depends_lib.

 Here is a log of the above example:
