Looks like you have the CXX variable exported in your environment somewhere -
possibly in make.conf or somewhere else? I can build this application in both
x86 and amd64 without any problems unless I export CXX and then it will fail in
a similar way. It would normally read,

g++ -c -march=k8 -O2 -pipe pairs.cc

Try unset CXX in bash, or checking for it make.conf.

I unsetted CXX and CXXFLAGS but it still fails

The ebuild relied on CXX set (which it can't any more) - changed. Please give
it a try when the corrected ebuild hits your portage mirror. Re-open if you
still have problems.
