Let's have a brief refresher course on what you installed and why you think you need 'emerge -e world' (I failed to keep the previous posts). If you installed Stage3, for example, you should have a reasonably current system, so I would just do 'emerge -upv world', review the pakcages and USE flags, and then either emerge manually or do 'emerge -u world.' 

Make a habit of using the -v[p] flags when doing emerge so that you are aware of prerequisites and optional USE settings (-v); -p gets you a dry run; remove it to do the emerge. For example, if a package indicates that in can take advantage of mysql, you might want to emerge mysql first and add USE='...mysql...' to your settings (/etc/make.conf); otherwise that functionality won't be included. If you were to install a source package manually, you would do ./configure with various optional flag settings. Gentoo does this automatically based on the USE settings you prefer.

'emerge -e world' will recompile/install everything you have which isn't really necessary unless you've got a major discrepancy between the machine you are running and the installed base.

HTH,
