As per https://github.com/owncloud/core/issues/23003 and after testing in my site, this USE requirement (not activated by default) should be set on new ebuild. Emerging php with this USE solved the issue.
Owncloud ebuild already has this dependency: RDEPEND="dev-lang/php[curl?,filter,gd,hash,json,mysql?,pdo,posix,postgres?,session,simplexml,sqlite?,xmlreader,xmlwriter,zip] virtual/httpd-php" And when YOU do a MANUAL installation of owncloud, as you wrote here: https://github.com/owncloud/core/issues/23003 how do you think this will work? You have two choices: - modify this Bugticket against dev-lang/php and ask the PHP Team to default enable xmlreader useflag, but I do not think that they will do so - or use the provided Ebuild, with the correct dependency
