Comment (by cjones051073):

 So just to document a bit where my limited tests have got to on the issues
 on < 10.9, the following is a small reproducer.

 {{{
 wget www.hep.phy.cam.ac.uk/~jonesc/macports/hello.tar.bz2
 tar -jxf hello.tar.bz2
 cd hello
 PATH=./stage0-x86_64/bin:$PATH cargo run
 }}}

 working output should be

 {{{
    Compiling hello v0.1.0 (/Users/chris/Downloads/hello)
     Finished dev [unoptimized + debuginfo] target(s) in 2.11s
      Running `target/debug/hello`
 }}}

 on < 10.9 I get the frustratingly cryptic

 {{{
 error: Unknown option
 }}}

 Been poking at this a bit, with various Dtrace utilities, but not really
 getting anywhere, so if anyone else has ideas ?
