You mean 3 lines of  ~80 characters of USE flags in make.conf?
That is a lot and shurely will come and bite you in the future.
I guess most of us learn a sane way to handle use flags the hard way,
just sharing,
these days my USE flags in make.conf are less than one line even less
than 8 flags,
I would say a good aproach is to select the right profile for your
need is the most important, check the flags that it has(emerge
--info), and then only the flags that you really really want on
*every* package you put in make.conf, everything else goes to
/etc/portage/package.use/my.use on a per package basis, and everything
else portage finds out it needs to build what i want goes to
/etc/portage/package.use/zzz_auto.use.
And keep your world to only what you need, learn about --oneshot as
soon as you can.

 i got an error with the rbind "mount --rbind /sys /mnt/gentoo/sys" i
should have guessed the stage3 was just compressed,
> and it also couldn't find a "sane" /dev.  probably both due to centos not playing nice (and my mounting and unmounting of a couple partitions).

I would recomed using something like the base livecd or systemrescuecd
for an install with OpenRC. and only use something like CentOS(if you
are talking about 7) if you want to use systemd,  and then make use of
systemd-nspawn and not chroot and bind mounts, and the systemd stage3.
