NS2 nam error

I have been bothered by this error while running ns/nam for a long time now. Finally found that tk needed patching :( Here is the error that I got and the solution that helped me fix it.

[root@localhost]# nam:
[code omitted because of length]
: no event type or button # or keysym
while executing
"bind Listbox {

%W yview scroll [expr {- (%D / 120) * 4}] units


invoked from within

"if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} {
bind Listbox {
%W yview scroll [expr {- (%D)}] units


bind Li..."

And, I got the solution to this on: http://forums.fedoraforum.org/showthread.php?t=206795.
Essentially you need to patch tk8.4.18 with the patches from: http://bugs.gentoo.org/show_bug.cgi?id=225999
