Found the offending line!  And ... it had nothing to do with the 
registerSpecialRenderer() call,

    // Verify that the RealFlow plug-in is in existence...
    if (!lookupIFDRealFlow()) {
        cout << "ERROR: Can't find Real Flow IFD!" << endl;

Which I had taken from the ROP_SimpleRIB.C example ... oops!

So now, not only does the registerSpecialRenderer() call work correctly, 
Houdini doesn't crash on Linux as it tried to load the ROP/IFD combo 
(can you spell relief!).

Peace in the meadow ...
