Calculating dependencies... done!

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# required by =x11-libs/wxGTK-3.0.5.1-r1::atlant (argument)
>=x11-libs/wxGTK-3.0.5.1-r1 -abi_x86_32

 * 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.
