 MacPorts has no way to track configuration files. Currently if a configuration file is part of a port it will get overwritten on every upgrade which makes it less useful. At the moment, many ports only install default configuration files and the user has to copy it to the original location. But this always requires manual action and the user is not informed of updates in this configuration file.
 
 For this task, investigate how other package management systems handle this. Find the best way to support it in MacPorts and implement it.

+==== Scan for broken dynamic libraries for rebuild ====
+
+Upgrading any port can naturally break its dependents if using dynamic libraries. The only way to fix this is currently rebuilding all dependents, no matter if necessary or not. MacPorts should get a new command to scan installed dynamic libraries and binaries for linker errors and mark the corresponding port for rebuild. After checking all files, broken ones should get rebuild in the correct order. Probably it has to do the check again after each set of rebuilds.

+If you are familiar with Gentoo, this would be the equivalent of the revdep-rebuild command. See #17473 for more information.
