No, but you're missing something that will seem obvious in retrospect:
Libtool VERSION_INFO triples don't correspond directly to SONAMEs.
The three elements of the VERSION_INFO triple are:
* CURRENT: The current version of the ABI. This increments whenever
a binary interface changes, or a new binary interface is added.
* REVISION: Which implementation of the "Current" ABI is this? This
is set to 0 whenever the ABI hits a new version, and increments by one
whenever
* AGE: With how many previous versions of the ABI is "Current"
version backward-compatible? This increments whenever the ABI changes
in a backward compatible way, and
According to the libtool source, different shared-library systems
build their version numbers in different ways. Linux does
"{Current-age}.age.revision"; freebsd does "current.revision"; Irix
gets downright weird, and so on.
So yeah; nothing to worry about here. :)
cheers,
