Calculating dependencies... done!
Dependency resolution took 16.10 s (backtrack: 0/20).


The following USE changes are necessary to proceed:

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.

 * In order to avoid wasting time, backtracking has terminated early
 * due to the above autounmask change(s). The --autounmask-backtrack=y
 * option can be used to force further backtracking, but there is no
 * guarantee that it will produce a solution.

!!! All ebuilds that could satisfy ">=dev-build/gn-0.2235" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-build/gn-9999::gentoo (masked by: missing keyword)
- dev-build/gn-0.2235::gentoo (masked by: ~amd64 keyword)

(dependency required by "dev-util/electron-37.0.0::gentoo" [ebuild])
(dependency required by "electron" [argument])
