When I ran $ mirrorselect -a -s4 -o | grep 'GENTOO_MIRRORS=' >> /mnt/gentoo/etc/make.conf during installation from a minimal live cd, mirrorselect reported: /usr/sbin/mirrorselect: line 1: portageq: command not found This message is confusing. It has no meaning to the casual user. It happens because the check for the portageq binary happens after the actual call to portageq.
Created attachment 47947 [details, diff] this patch surpresses the message
This is not an issue in the upcoming version of mirrorselect.
