If you have already grabbed 1.1.1, you should apply this patch to the
file ns-src/cmu/scripts/run.tcl.  This patch fixes a bug which
prevented ns from reading older style scenario files...

I also added a definition of AF_LINK to packet.h, because Linux
doesn't seem to provide one.

These bugs are fixed in our release 1.1.2
