IIRC you get the same error when there is a linker error. Try actualy
executing it from the shell. You should see:

uml_net : bad argument list - if you're running uml_net by
hand, don't bother.  uml_net is run automatically by UML when
necessary.

If you do and it still does not work, it will probably be time to look
at the code, why this might actualy happen.
