This is one of the design problems we have. If you install port A
version 1, that declares a (pre|post)-deactivate hook and then
upgrade your dports/ tree with the new portfile for version 2 that
does not declare the hook, then the very hook is no longer stored
anywhere in your disk.
We should save the whole portfile in the receipt to be able to
implement that feature.
I believe this also applies to dependencies. If port A version 1
depends on port B and version 2 does not depend on port B, port(1)
will let you uninstall B without telling you you are breaking port A
