Fixing NAM bug

I am using ns-2.31 on Ubuntu and had this error message when i tried to run 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..."


I found two patches to solve this problem from http://bugs.gentoo.org/show_bug.cgi?id=225999

i made correction to both files as
