libxml (or one of its subpacakges) has multiarch conflicts when installed for both i386 and x86_64 in the Fedora development tree. For help in resolving them, see http://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks. file /usr/bin/xml-config from install of libxml-devel-1.8.17-17.fc8 conflicts with file from package libxml-devel-1.8.17-17.fc8 (Note that this is an automated bug filing.) It would be nice to have these bugs fixed by the beta of Fedora 9.
This should be fixed in libxml-1:1.8.17-18.fc9 http://koji.fedoraproject.org/koji/buildinfo?buildID=22483
