Comment (by cjones051073):

 So, as it happens before finding this ticket I had been looking into
 getting rust going on older systems, just for kicks..

 Anyway, the approach I took was quite similar to what was discussed here.
 Thanks though for the tips w.r.t. optool above as that simplified what I
 was trying to do somewhat...

 I've pushed what I have to

 https://github.com/macports/macports-ports/pull/10740

 Works just fine on 10.9. Older systems have issues ... building rust there
 fails when the build starts with

 doing a web search for 'cargo error unknown option' finds a number of
 discussions (mostly how hard debugging cargo/rust is) but nothing yet that
 helps me figure out what is wrong..
