Increasing the system performance

Hello,
I am running Calculate Linux Gnome x64 and I am trying to Increasing the system performance by running emerge -e world but it fails. I get this output from the terminal:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy "media-libs/raptor:2[xml]".
!!! One of the following packages is required to complete your request:
- media-libs/raptor-2.0.7::gentoo (Missing IUSE: xml)

Try run <>, after this run <<emerge -uaDN world>> again

Thank you very much for the help, it is running now! I will post back once it is done. :slight_smile:

Ok so everything went fine with that command, sorry took so long to reply but I could not check the status until I got home from work. Thanks again for your help and the OS is running great! :slight_smile:
