However there is a potential problem if different packages do require
different versions of (say) bdb4. If you're compiling multiple packages,
and the first one installs 4.5 because that's ok for it, you can have
that the next one requires 4.6. Which means really that all packages
that have linked to 4.5 must be relinked (and therefore usually
recompiled) with 4.6.

I must say I am surprised about the way FreeBSD handles this with its
portupgrade tool, since its shared libraries don't even *have* the minor
version in the file name.
