These are my make.conf vars:

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=native -O2 -pipe"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j7"

So far, I have this package masked while ziproxy 3.3.1 emerged normally and it's working without any issues. I wonder what changed in that "-r1" release that breaks my emerge.
