Download Ncview from:
http://meteora.ucsd.edu/~pierce/ncview_home_page.html
Uncompress it:
tar -zxvf ncview-2.1.2.tar.gz
Install some required libraries (already installed on model machine):
yum install gcc
yum install libX11-devel.x86_64
yum install Xaw3d-devel-1.5E-15.1.el6.x86_64
yum install libpng-devel-1.2.49-1.el6_2.x86_64
Try to configure ncview::
./configure --prefix=/opt/ncview/2.1.2

ln -s cd /usr/include/X11/Xaw3d/ cd /usr/include/X11/Xaw
