Today, it does not -- the location has to be compile-time
initialized. So if you move the library+plugin somewhere else, the
Etnus scheme to find the DLL currently cannot handle it.

We have proposed a new scheme to Etnus and Allinea that allows a bit
more flexibility to find the DLLs at run-time; both have agreed to the
idea in principle. We will include this support in Open MPI v1.3; I
don't know when/if the debuggers will support it. I believe that the
ball is currently in my court; Etnus asked me some questions to which
I have not yet replied... doh...
