RHEL-6.4 is released and include php-5.3.3-22.el6 which provides the
missing dependencies in php-* packages
In php-common
php(language)
php-core
php-ereg
pgp-filter
php-phar
php-standard
In php-xml
php-xmlreader
php-xmlwriter
So, as in fedora, all provided extensions have, now, their virtual provides.

Remi.
P.S. perhaps we have to wait a little, to have clones of RHEL synced
with this changes.
