I've just work a little on the final 1.8.0 :

http://rpms.famillecollet.com/SRPMS/php-pear-1.8.0-2.fc10.remi.1.src.rpm http://rpms.famillecollet.com/fc10.i386/php-pear-1.8.0-2.fc10.remi.1.noarch....

Changed

• PEAR 1.8.0RC1
• Archive_Tar 1.3.3
• www_dir set to /var/www/html (so, pear must own it)
• install-pear.php revision 1.37

New changes : - PEAR 1.8.0 - XML_Util 1.2.1

PEAR now Requires XML_Util (it previously use a bundled class)

So XML_Util must be provided by php-pear and php-pear-XML-Util will be obsolete.

This packaging change requires an awful %triggerpostun (because php-pear-XML-Util unregister the module during %postun which then should be re-registerer...) Another solution will be welcome...

Regards
