I don't understand this

[Paul Schmehl]

I upgraded a server from php4 to php5.

First I uninstalled php4.  Then I uninstalled php4-extensions.  Then I 
installed php5.  Then I installed php5-extensions.

Now, when I run portupgrade, I get a ton of complaints about php4 
extensions that can't be updated.

portupgrade -ai

So, I started uninstalling those ports, but I discovered that the 
uninstall was removing files installed by the php5-extensions install. 
So, I had to uninstall each php4 extension, then uninstall each of the 
corresponding php5 extensions and then reinstall them in order to get the 
ports db straightened out and have the correct files on disk.

Surely there's an easier way to do this?  What did I miss?  And why 
doesn't the php4-extensions port uninstall each of the ports installed?
