As far as OpenBSD is concerned, version info <current>:<revision>:<age>
results in lib<name>.so.<current>.<revision>, ignoring age completely.
That said, the package team decided to takeover library versioning in
ports. So anyway I do not think it is really necessary for you to try
to come up with a portable scheme wrt versioning, as it will eventually
be controlled by the packagers. They just need to be informed of backward
compatibility issues between releases to know if a major bump is required
or not.
