dont understand emerge errors

Hi, so I'm using Funtoo but I figured its Portage shouldn't be too different from Gentoo's. This is my first installation and I've only just finished getting the desktop environment to work and installing a couple of programs.

You have to emerge packages as root because only root can write to the entire filesystem to add the package.
Either log in as root with "su -" and the root password, or use "sudo su" and your user password if your system
is set up that way.

It looks as if you need to set the qt4 or qt5 flag somewhere, at least to emerge vlc.

Moved from Portage & Programming to Unsupported Software.

Funtoo is not offically supported. That does not mean that this thread will not get support.
It avoids Gentoo uses following a thread that may not work for them.

Using su and sudo to run commands with root user privileges can have different results, as you can see in the examples below. Most Ubuntu users only know about the sudo command, as su is disabled by default in Ubuntu. In other distributions I use su to become the root user when performing administrative tasks, in order to avoid any unforeseen problems due to the path and environment.

Path and home directory of your user account

Look at the path and default (home) directory when I am logged in under my own user name (fitzcarraldo):

fitzcarraldo@meshedgedx ~ $ echo $SHELL
/bin/bash
fitzcarraldo@meshedgedx ~ $ whoami
fitzcarraldo
fitzcarraldo@meshedgedx ~ $ echo $PATH
/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.3:/usr/games/bin
fitzcarraldo@meshedgedx ~ $ cd ~
fitzcarraldo@meshedgedx ~ $ pwd
/home/fitzcarraldo
fitzcarraldo@meshedgedx ~ $

Path and home directory when you use sudo

Now let's see what the path and default (home) directory are when I use the sudo command:

fitzcarraldo@meshedgedx ~ $ echo $SHELL
/bin/bash
fitzcarraldo@meshedgedx ~ $ sudo -s whoami
Password:
root
fitzcarraldo@meshedgedx ~ $ sudo -s echo $PATH
/usr/local/bin:/usr/bin:/bin:/opt/bin:/usr/x86_64-pc-linux-gnu/gcc-bin/4.8.3:/usr/games/bin
fitzcarraldo@meshedgedx ~ $ sudo -s cd ~
fitzcarraldo@meshedgedx ~ $ sudo -s pwd
/home/fitzcarraldo
fitzcarraldo@meshedgedx ~ $

fitzcarraldo@meshedgedx ~ $ sudo -s
Password:
meshedgedx fitzcarraldo # echo $SHELL
/bin/bash
meshedgedx fitzcarraldo # whoami
root
meshedgedx fitzcarraldo # echo $PATH
/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/opt/bin
meshedgedx fitzcarraldo # cd ~
meshedgedx ~ # pwd
/root
meshedgedx ~ # exit
exit
fitzcarraldo@meshedgedx ~ $

N.B. The sudo man page tells you that the -s (shell) option runs the shell specified by the SHELL environment variable if it is set or the shell as specified in /etc/passwd (the password database). If a command is specified, it is passed to the shell for execution. Otherwise, an interactive shell is executed.

Path and home directory of the root user

Now let's see what the path and default (home) directory are when I am the root user:

fitzcarraldo@meshedgedx ~ $ su
Password:
meshedgedx fitzcarraldo # echo $SHELL
/bin/bash
meshedgedx fitzcarraldo # whoami
root
meshedgedx fitzcarraldo # echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin
meshedgedx fitzcarraldo # cd ~
meshedgedx ~ # pwd
/root
meshedgedx ~ # exit
exit
fitzcarraldo@meshedgedx ~ $

Summary

As you can see above, the path and default directory are not the same if you use the sudo and su commands.

sudo -i is more elegant.

The message was saying you can not have both qt4 and qt5 enabled.

The '!' mark is saying NOT.
So for this statement qt4? ( !qt5 ) Is saying: If qt4 is set then qt5 can NOT be set.

LotSX,

The error also says

Thanks, removing the USE flags until there was only one solved the problem.

I'm still having trouble understanding the error outputs from my emerge, though. I ran emerge -uavDN @world | wgetpaste and this is the output: https://bpaste.net/show/d93786ef9ee6 . From the looks of it, I think there's a conflict between two patches of xorg-server. How can I solve that?

EDIT: This part did not get into the bpaste for some reason:
