[ns] installation problems

[Suet Fei Li <suetfei@bwrc.eecs.berkeley.edu>]

Hi I have the following problem installing ns-2.1b6 on Unix (Sun platform).
Does anyone know what I should do?

I installed the newest version of NS: ns-allinone-2-2.1b6 without problems.
The I tried to compile the ns-2-snapshot-20000830 instead of the supplied
ns-2.1b6.  The compiler complains:
--------------------------
