This seems to me that you may have accidentally edited the first line of
ns-packet.tcl to remove the comment symbol "#".  Can you make sure that
your first line reads:
# -*-   Mode:tcl; tcl-indent-level:8; tab-width:8; indent-tabs-mode:t -*-

Thank you for testing the ns-2 release candidate.  Here is a brief update
on the status.  I've not made a release yet since I am aiming to fix all of
the 64-bit issues for those models covered by the regression tests, before
making the release.  I am getting close; there is one remaining issue to
fix with the web models that result in divergent traces in 32-bit and
64-bit (due to passing web page pointers to Tcl space and back again).  I
expect to get some time to finish that off this month.
