Compatibility numbers are not compared across major library versions because client images use specific major libraries. You should not get into a situation where you are comparing libjpeg.8.dylib compat 13.0.0 and libjpeg.9.dylib compat 11.0.0. > So if libjpeg is to be maintained as a 3rd alternative a patch will be > required to change the compatibility and current version that is stored in > libjpeg.8.dylib . We should not roll back a library's compatibility number. Doing so presumes that the newer version is backwards-compatible with the older version. It would make more sense to bring libjpeg-turbo up to compatibility version 13.0.0. vq _______________________________________________ macports-users mailing list [email protected] https://lists.macosforge.org/mailman/listinfo/macports-users
