Well, you can always emerge crossdev and crossdev i686-pc-linux-gnu then... (-: PS: A quick check on my system shows this: # [08/12 13:27:52] xenon@ribosome ~ $ gcc -m32 -v --version 2>&1 | grep LIBRARY_PATH LIBRARY_PATH=/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/32/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib32/:/lib/../lib32/:/usr/lib/../lib32/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/lib/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../:/lib/:/usr/lib/ # [08/12 13:28:00] xenon@ribosome ~ $ gcc -v --version 2>&1 | grep LIBRARY_PATH LIBRARY_PATH=/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64/:/lib/../lib64/:/usr/lib/../lib64/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/lib/:/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../:/lib/:/usr/lib/ So the lib32 paths are actually included in the library search path, and correctly placed *before* the lib counterparts. I'm not sure how your toolchain ends up in the state you described, but it's certainly weird... Can you please provide the output of "emerge --info" and "gcc -v --version"? This way people will have more clue to help you...
