Please filter your script with `ansifilter` to remove ANSI colour control codes.
Otherwise, output is remarkably difficult to read with the majority  of  pagers.
I've filtered further quotations for you.

This does not really indicate an error in your make.conf file; you just need  to
build Polkit with EITHER the `elogind` or `systemd` flags set, but you  probably
don't want to set these flags globally.  Polkit is pulled in as a dependency  by
the listed packages.

Unless you're using systemd, add the following to  your  `package.use`  listings
and see if the issue is resolved:

        sys-auth/polkit elogind

This restriction is defined at [1], using the built-in XOR  "^^"  operator  [2].
The "exactly-one-of" terminology is used to save non-developers  the  hassle  of
trudging through the on-line Development Manual to find the meaning  of  obscure
notations.
