Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

!!! All ebuilds that could satisfy "x11-libs/libdrm[libkms,video_cards_vmware]" have been masked.
!!! One of the following masked packages is required to complete your request:
- x11-libs/libdrm-9999::gentoo (masked by: missing keyword)
- x11-libs/libdrm-2.4.102::gentoo (masked by: )
