Both mirrorselect-2.2.0-r1 and mirrorselect-9999 in gentoo-x86 are now fully prefix capable without need for additional prefix patching. One exception seems to be in all versions of mirrorselect. mirrorselect's use of netselect does not work in prefix, but does in non prefix installs. Reproducible: Always
thanks, now using the gx86 version!
