[ns] problem with installation on Linux

[Liang Qin <lqin@sce.carleton.ca>]

Hi there,

When I installed all-inone-2.1b6 on my Linux PC(red hat 6.1), I got one problem:
here is the error message:

-------------------
./mkLinks /home/lqin/ns-allinone-2.1b6/tkbox/man/mann

Could anyone give me a suggestion?

I used ns2 for several months on this PC, today I just tried to re-install it.

Thanks!
