+Building addons with dependencies:
+----------------------------------
+The build method described above excludes addons that depend on runtime libraries.
+This is because the installed versions of the dependend libraries on the build-machine
+and the target machine have to match exactly. Therefore this addons cannot be

+
+Distribution package maintainers and users who build the addons on their target machine
+can enable the build of addons with dependencies:
+
+./configure --enable-addons-with-dependencies
