Making sure you have emerged gentoolkit (emerge gentoolkit)

euse -i bash_completion

The output is

global use flags (searching: bash-completion)
************************************************************
[+ C  ] bash-completion - Enable bash-completion support

local use flags (searching: bash-completion)
************************************************************
no matching entries found
