You need to change your version to 33.0 or 34.0 in package.xml.<br/> 
`<version>34.0</version>`<br/>
If not you can add a `<processMetadataValues>` section to your process builder meta data file.<br/> 
Instead of `<members>*</members>`, provide the excact name of your process and active version number. 
`<members>My-process-10</members>`. Where "My-process" is the name of your process and "-10" is the active version.<br/>
Once you deploy a processes to the target org, you need to activate it manually.
