There's no dependency relation between libxml2 and libfontconfig-common, so #4 wouldn't fix the problem. And some of the other suggestions would require work on setup.exe that someone would have to do. The current problem is simple to fix and shouldn't have to wait for that. I like your idea of using perpetual postinstall scripts. I think the way to do it is probably to make fontconfig_dtd.sh perpetual with prefix "zp_". That way if libfontconfig-common is installed without libxml2 but then libxml2 is installed later, the xmlcatalog command gets run. We would have to check that no harm is done if that xmlcatalog command gets run more than once. Ken
