* the version of Tracker the application or module was compiled
* against.
*
* Compatibility is defined by two things: first the version
* of the running library is newer than the version
* @required_major.@required_minor.@required_micro. Second
* the running library must be binary compatible with the
* version @required_major.@required_minor.@required_micro
* (same major version.)
*
* Return value: %NULL if the Tracker library is compatible with the
* given version, or a string describing the version mismatch.
