[ns] Mac Trace Problem

[Devendra Goyal <goyald@email.uc.edu>]

Hi,
Strange problem, possibly some bug, please help.
If I set MacTrace ON for AODV or DSR routing in ns-2.1b6, I get the
following error:
drop-target lookup failed

    (_o23 cmd line 1)
    invoked from within
"_o23 cmd drop-target _o33`"
    invoked from within
"catch "$self cmd $args" ret"
