Hi Bala: There should be a package called something like libstdc++6 that you need to install. You might want to ditch redhat/fedora for Ubuntu. Ubuntu is 100% free, the repositories are freely accessible and easy to use, it has great internationalization, and is an absolute pleasure to use compared to rh/fc. http://www.ubuntu.com/ You can download and burn a disk image that you can boot from if you want to try it out. A new release (Gutsy) is scheduled for sometime in October (6 days from now), but I am already using it and can verify it works fine with phenix and everything else I can think of (coot, ccp4, cns, O, ...). http://tinyurl.com/2a2rkk The default window manager is gnome, but KDE (kubuntu) and Xfce (Xubuntu) are also available. I recommend installing the default one first, and then you can simply download the others to try them out.
