Comment (by ballapete):

 Replying to [comment:10 kencu]:
 > Your build attempt is somehow still calling `/Developer/usr/bin/libtool`
 as you can see, which does not work to link object files built with
 clang-3.9 on 10.6 as it's too old.

 Indeed:

 {{{
 -- Found libtool - /Developer/usr/bin/libtool
 }}}

 >
 > The fix I suggested above changes that to `/opt/local/bin/libtool` from
 cctools, which does work. Please check that bit carefully in the llvm-4.0
 build file you edited and see if you altered it correctly. Or as I said in
 your other ticket, just check out my SnowLeopardPorts repo where it is all
 done for you.

 Or did I miss the proper `build file`?

 understands bootstrapping dependencies much better than I do. Obviously he
 is very busy these days.
