Compiler error doing hello world

[v21]

I'm seeing this:

v21s-Mac:~ v21$ RUST_LOG=rustc=1,::rt::backtrace rustc test.rs
rust: task failed at 'failure in execvp: No such file or directory', /private/tmp/rust-DnEq/rust-0.7/src/libstd/run.rs:689
error: internal compiler error: unexpected failure
note: the compiler hit an unexpected failure path. this is a bug
note: try running with RUST_LOG=rustc=1,::rt::backtrace to get further details and report the results to github.com/mozilla/rust/issues
rust: task failed at 'explicit failure', /private/tmp/rust-DnEq/rust-0.7/src/librustc/rustc.rs:354
rust: domain main @0x7f9014008410 root task failed

test.rs is literally just:

fn main() {
println("hello world");
}

This is running within a VM, if that's relevant.

It seems to be failing because gcc isn't in your PATH.

Please re-open if this just wasn't caused by gcc being unavailable.
