Comment (by jeremyhu@…):

 Replying to [comment:45 mopihopi@…]:
 > I had resolved this on my system by building ld64 @236.3_1 with
 clang-3.4, however during an update today, MacPorts automatically
 "updated" it to the old version @136_2 :(.

 Yes ... so as to not block everything dependent on ld64 ;)

 > ld64 @236.3_1 should build on Snow Leopard if all versions of gcc are
 blacklisted.

 Yes, however that causes a dependency cycle.  clang depends on ld64.

 > There is also now a current Snow Leopard binary archive for all of the
 clang versions, allowing the circular dependency issue to be avoided to
 build ld64 from source when clang-3.x is not already installed.

 That's not really a valid argument.  We need to ensure there is no cycle.
