Have you run revdep-rebuild?  It searches all of the .so files, looking 
for dependencies broken by an upgrade, then rebuilds the packages with 
broken files.

Is "dev-php/php" in your world file (/var/lib/portage/world)?  If 
"emerge -e world" didn't rebuild it, there's a good chance PHP is not 
actually listed in your world file.  Note that dev-php/php seems to be 
PHP4, while dev-lang/php is PHP5.  Make sure you're asking for the one 
you want.

Use "emerge -p --depclean" to find out what packages would be skipped by 
"emerge -e world".  On a clean system, "emerge -p --depclean" should 
list no extraneous packages, but note that "emerge --depclean" is often 
too zealous about uninstalling packages, so be careful.  Try "emerge -p 
--depclean | grep -i php" in particular.

BTW, use dispatch-conf rather than etc-update.  dispatch-conf 
automatically keeps a record of changes.
