[lldb-dev] Building lldb on OS X

[Todd Fiala]

Ok.  Definitely sounds worth of opening up a llvm.org/bugs ticket on.  That
way you can attach your make logs and whatnot.

Based on what you reported so far, it sounds like perhaps the build is
picking up headers from the wrong place (i.e. maybe configure is finding
the wrong llvm code, or something that is causing headers from one place to
get used with code from another, perhaps between the local lldb and
llvm/clang code).
