Dependency error when trying to install Blender on Gentoo

Question

I am trying to install Blender on gentoo using emerge, this is the error message i recieve:

sudo emerge --ask media-gfx/blender

 * IMPORTANT: 16 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.


 * IMPORTANT: 2 config files in '/etc/portage' need updating.
 * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
 * sections of the emerge man page to learn how to update config files.

These are the packages that would be merged, in order:

I already tried adding the flags, cpu flags, updating the system, and nothing seems to work.

Answer 1

on your first error it states that you should have one of listed flag inside CPU_FLAGS_X86

inside your make.conf CPU_FLAGS_X86=""

wiki article about this variable: https://wiki.gentoo.org/wiki/CPU_FLAGS_*

I'd suggest to use cpuid2cpuflags to get flags you'd like to put inside (it will list what your current CPU supports)
