Distributing components separately doesn't allow you to avoid the
terms of the GPL.  From your description above, it sounds like what
you are doing is OK, but I'm not familiar with these tools, so it
would help if you could describe more clearly exactly how the Eclipse
plug-in and the DBGP based debug engine are connected (to each other
and to Octave).

Parts that link with Octave (either dynamically or statically, to form
a single executable program) must have GPL-compatible licenses.
Communicating over a network protocol is not linking, so if
your Eclipse plug-in is only linked with Eclipse and not Octave, and
only communicates with Octave over a network connection (so that
Octave is running in a separate process) then the plug-in may have any
license you choose (though I would hope it would be a free software
license).
