I think you have to given the versioning rules.  And for gdbm too et al too.

Its certainly not ABI/API compatible.  Speaking of which why wasn't this
only in 1.4.x/trunk(2.x) ?

Excellent, Bojan, now I've got the history and why, and understand whats
happened.  I don't think teaching subversion about this fact will be
sufficient --

There are over 56 apps in the freebsd ports tree with over 900 depends
that this breaks as is, though most of which indirectly depend on
subversion.
