current stage 3 installation does not allow most packageges to be successfully emerged because of a bug in chmod (suid) that gives permission denied even to root. amoung things that cannot be installed is system logger, and nullmailer.

What stage3 tarball did you use? "Current" is not the right answer.
Also, post the output of `mount'.
The specific stage3 used was stage3-amd64-hardened-20130411.tar.bz2 the problem occurs in the chroot environment of the initail install the device /dev/sda3 is ext4 formatted fs mounted on /mnt/gentoo and chroot to /mnt/gentoo after extracting the stage3. This is all run in a Vmware virtual machine - the scsi controller is paravirtual and the network card is VMXNET 3.

What CD are you using for the install? Does the CD have any hardened features enabled? Please check if you have /proc/sys/kernel/grsecurity/ and in particular make sure chroot_deny_chmod is not set to "1".
--- Comment #6 from Jorge Manuel B. S. Vicetto <jmbsvicetto@gentoo.org> --- What CD are you using for the install? Does the CD have any hardened features enabled? Please check if you have /proc/sys/kernel/grsecurity/ and in particular make sure chroot_deny_chmod is not set to "1". The cd is admincd-amd64-20130411.iso all the stuff in /proc/sys/kernel/grsecurity is set to 1. This seems to be the trouble as I was later able to install the offending stage3 successfully by booting of an older (2012) install cd.

I asked because I already knew the admincd had those features enabled. Since the admin-cd is meant for system recovery, but can also be used for new installs, I'll have to think and talk with others about this. One option would be to add a script (init script?) to disable the hardened features that anyone can run to prevent these issues.

I just checked with the latest admin-cd[1] and this has been fixed. [1] - http://distfiles.gentoo.org/releases/amd64/autobuilds/current-admincd-amd64/admincd-amd64-20150611.iso
