Missing PHP libraries after 10.0-RELEASE upgrade

[nano]

During my upgrade from 9.2-RELEASE to 10.0-RELEASE the ports tree was 
broken [0]. This upset the standard freebsd-update major release upgrade 
process [1]: at the portmaster -f point, most builds failed due to the 
STAGEDIR debacle. By the time the ports tree was fixed and I was able to 
successfully reinstall all ports, the final freebsd-update install 
command returned the message that there was nothing to do. I rebooted 
and thought nothing of it. A couple days later, I've tried to update 
lang/php55 and all lang/php55-extensions to 5.5.8 (from 5.5.7); PHP 
successfully updated but all extensions are failing due to missing
libraries:


/usr/ports/lang/php55-extensions # make install clean

I am running into the same problem on both systems that I upgraded from 
9.2-RELEASE [2].

How do I fix this?

Thanks.
