problem with installing ns

["Siavash Khorsandi" <siavash@nortel.ca>]

Hello every one,

When I try to install NS, Tcl and TK goes through well but I get the 
following error meesage in Otcl:

rm -f libotcl.sl otcl.o so_locations
gcc -c -g -O2  -I. -I../tkbox/include -I../tclbox/include -I/usr/include/X11R5 -I/include  otcl.c
ld -b -o libotcl.sl otcl.o
/bin/ld: Invalid loader fixup needed
collect2: ld returned 1 exit status
make: *** [libotcl.sl] Error 1

I appreciate any suggestion on how to resolve this.
Thanks,
Siavash
