At a terminal prompt, try these commands: [morganm@morganm_fc3 ~]$ su - Password: [type your root password here] [root@morganm_fc3 ~]# yum install compat-libstdc++ At that point, yum (one of Fedora's built-in installer/system updaters) will look for, download, and install the compat-libstdc++ package. Read up on yum (among other things) at fedorafaq.org, it's really useful.
