According to my notes from back then, I apparently did get Rust to
build on my 10.5 Mac once, back in March 2011 (the pre-0.1 days).  But
all my notes say is that I had to use gcc 4.2 rather than 4.0.1 (Xcode
should come with both, although 4.0.1 is the default) to get it to

Unfortunately, I didn't go into any more detail than that, and now I
wonder if I was hallucinating.  In the time since then, I've tried
several times to build it, but something has always gone wrong while
building rt -- a missing header file, I think.  I've never seen the
error that Ralph had, though.  Trying it again just now, I got this:

/Users/lkuper/rust/src/rt/rust_sched_driver.cpp: In member function
'void rust_sched_driver::start_main_loop()':
/Users/lkuper/rust/src/rt/rust_sched_driver.cpp:33: error:
'pthread_setname_np' was not declared in this scope

I don't think it should be impossible to make work, but I never had
the energy to dig in, and I never supposed that anyone else cared
about 10.5 -- apparently, I was wrong about that!  :)
