sure, you have built a package depending on a os library such as 
libmysqlclient.so, and you would like the native operating system to 
take care of security fixes etc, but you want to signal to the os that 
your package depends on those libraries and therefore do not allow a 
user to uninstall the library (in this case libmysqlclient.so) OR 
upgrade it to a incompatible version.

If your package is 100% pure perl, then of course this is un-necessary.
