Follow the doc and don't try to put the bundle insde the JVM installation path. 1 - Check if you have a libxml2.so in the php bundle. If not something went wrong will building. 2 - Use ldd libphp5.so and LD_LIBRARY_PATH to find the right value for LD_LIBRARY_PATH 3 - Use nm on libxml2.so to check that xmlTextReaderSchemaValidate is an exported symbol.
