Is this dependency among plugins because you are referring to some
classes defined my plugin A in plugin B? If so, you might be better
off creating a library for the common classes and then have the two
plugins depend on it. You'll have to use LD_LIBRARY_PATH or rpaths to
ensure that the shared libraries are loaded when the plugins are
loaded. ParaView currently does not guarantee any order when trying to
auto-load the plugins at startup. That  may be something worth
investigating.
