That was my understanding as well, and I allowed gcc the default installation directory of
/usr/local. But what seems to be happening (confirmed by using -Wl,-M to trigger a link map from the
linker) is that the g++ in /usr/bin is attempting to link to /usr/local/lib/libstdc++.a, and the
g++-3.1 in /usr/local/bin is attempting to link to /usr/lib/libstdc++.a, and I'm not sure why. It's
probably an installation SNAFU on my part, but I'm having a hard time tracking it down.
