Pkgdb -F is what screws up the installed ports registry. Here is an 
example of what happens:

1. port-A needs dependency port-B installed
2. port-B is installed
3. port-A is installed and marks its registry as being dependent on 
port-B

and here is where things go wrong using sysutils/portupgrade:

4. port-B gets upgraded to port-B.1 and portupgrade reports port-A
has a stale dependency.

  Then you run pkgdb -F and port-A's registry is changed to say it was 
built with port-B.1, portupgrade claims this "fixes" the registry when 
it really breaks it.

Remember, port-A was built with port-B, not port-B.1 and the correct way 
to "fix" the stale dependency is to upgrade port-A so it is built with 
the newer dependency.

sysutils/portmanager also updates ports, put it doesn't cheat. When
port-B became port-B.1 portmanager will rebuild port-A using port-B.1
as the dependency.  port-A's registry stays reliable, reflecting how the
port was really build instead of how we wished it were built.
