[gentoo-user] emerging package with rR?

[n952162]

Hello,

can someone explain why rR?

    [ebuild  rR    ] virtual/perl-Pod-Parser-1.630.0-r8::gentoo  0 KiB

Why would this be happening?

               r   reinstall (forced for some reason, possibly due to
slot or sub-slot)
               R   replacing (remerging same version)

I had 181 packages to install.  It completed, but with one restart, so I
re-ran the emerge to make sure everything was done:

    + emerge --getbinpkg n -v --tree --deep --update --noreplace
    --changed-use --binpkg-changed-deps=n --binpkg-respect-use=n
    --verbose-conflicts --keep-going --with-bdeps=y --backtrack=100 @world

Now there's 177 packages to install (no --sync in between).  Most ar rR.
