Comment (by maxkalashnikov-macports):

 That doesn't seem to work, though having `ld64+ld64_xcode` installed
 eliminates `ld64` from the list of dependencies in the error message:

 {{{
 --->  Computing dependencies for clang-3.9......
 --->  Dependencies to be installed: cctools llvm-3.9 clang-3.8 clang-3.7
 llvm-3.8
 Error: The following dependencies were not installed: cctools llvm-3.9
 clang-3.8 clang-3.7 llvm-3.8
 To report a bug, follow the instructions in the guide:
     http://guide.macports.org/#project.tickets
 Error: Processing of port clang-3.9 failed
 }}}
