After doing a make install (of an early rust-0.3.tar.gz) on top of an already installed Rust (from git a few days ago), I now get the following error while compiling things:

joshua@icfp:~$ cat > hello.rs
fn main(args: ~[str]) {
    io::println("hello world from '" + args[0] + "'!");
}
joshua@icfp:~$ rustc hello.rs
hello.rs:1:0: 1:0 error: multiple matching crates for `core`
hello.rs:1 fn main(args: ~[str]) {
           ^

There should be logic to override with newer versions, or otherwise warn about this sort of thing.
