If the library version number change is being made with the approval of the developers then of course that's fine. It's just weird when a library version number decreases. That should normally never happen. Usually also the library version number is not tied directly to the package version number. There's no reason why they should be related. For example, libiconv 1.14 installs libiconv.2.dylib, compatibility version 8.0.0, current version 8.1.0. gettext 0.18.3.1 installs libintl.8.dylib, compatibility version 10.0.0, current version 10.2.0. _______________________________________________ macports-dev mailing list [email protected] https://lists.macosforge.org/mailman/listinfo/macports-dev
