Well, for librairies postinstall makes the list of obsolete files/links
dynamically, by keeping only the last version of the dynamic librairies
in each directory. So in your case you downgraded from current to
netbsd-3, but you still have old (but unused because the symlinks properly
points to the release versions) current library, with minor numbers
highter than the ones from the release. So postinstall wants to
keep the old current ones which are, in fact, the one that are obsolete.
You have to remove by hands these old libs, postinstall can't deal with that.
