 OSX 10.6.7

 XCode 4.0 Build 4A304a

 The compiler used was /Developer/usr/bin/llvm-g++-4.2

 I noticed when debugging a segfault, even though my binary was linked to
 the Qt_debug libraries no line numbers or other symbols were available.
 My investigation found that no -g flags were passed to the Makefile.Debug
 LFLAGS, thus when the shared library was built the symbols disappeared.

 I added the flags (-g -gdwarf-2 like what was in CXXFLAGS) and rebuilt Qt
 and retried my gdb session.  I got symbols, line numbers, code listings,
 etc.

 This problem was first posted to the mailing list
 (http://lists.macosforge.org/pipermail/macports-
 users/2011-October/025840.html)
