 correctly is `ld64 +ld64_xcode` (ie "no MacPorts ld64" but that's another
 tale...).

 I agree with ken. Check the toolkit you have installed.i.e.

 {{{
 sudo port sync
 sudo port -f uninstall ld64
 sudo port -f uninstall cctools
 sudo port install cctools
 }}}

 then you should have the current defaults, which should work OK. (removing
 cctools might not really be needed, but does no harm...)
