gentoo hardened issue with emerging libpng

[erg_samowzbudnik]

Hi all,

I'm trying to get the hardened profile working but I'm getting stuck.
After having emerged the gcc, libc and binutils the 'emerge --emptytree world' stops at media-libs/libpng, it won't install.
It does compile but will not install. Any ideas what could have gone wrong?

here is the last bit of the log:

Any ideas?

ok, I've managed to solve it partially by reemerging libpng
now it emerges despite slot conflict.
It seems to be unrelated to the changed profile though,
just an ordinary slot conflict :-/
