That doesn't all logically follow (beyond ABI). It seems you mean "major version number increment, without backwards-compatible API support" (which can be coped with), but that was not at all clear earlier. > debian/ubuntu/etc. add the so major number to the package name: > xchat-otr and friends can still depend on libotr2 for a while, until > they update their code, while the new pidgin-otr can depend on libotr5. > Surely pkgsrc supports some equivalent notion? Yes - when upstream packages don't provide API back-compatibility, then there are packages with the version number in the name (not a shlib number). Or one without, that's "normal", and one or more with. For unstable upstreams, there is typically always a version. So then: are the set of files installed by these two versions distinct, so that they can not conflict, or is a system limited to at most one? But it may be that only pidgin-otr in pkgsrc uses libotr; if so it's easier to just upgrade both at once and leave the old libotr behind. Do the old libotr and the new interoperate? Specifically, if one person is running the current pidgin-otr/libotr, and another both new ones, can they still talk? (Sorry if I sound cranky; I'm not really trying to complain about how things are, just to point out that the questions I'm asking are the key questions one needs to have answered to decide what to do, and that they are missing from the pre-release announcement.)
