Error in NS2.35 installation on fedora 17 - networking

Question

I'm trying to install NS2.35 on fedora 17 using allinone package.
I'm new to linux environment and have already spent many hours trying this. So far I've found out it is a problem with dependent packages. But I'm not able to figure out following error.
Please help.
