Yes, I use MacPorts to install the prereqs for GnuCash.  In Mavericks 
they switched entirely to using libc++, I think because Apple did.  You 
can't use libstdc++ to build things with MacPorts anymore.  The version 
of WebKit they include builds ok that way, but I build the X11 version 
not the native version.

I found my stupid mistake and GnuCash now builds ok with clang for me 
(a lot faster too).  I do both an optimized and a debug build.  The 
optimized build works ok, but the debug build crashes trying to produce 
a vendor listing report.  It's an EXC_BAD_ACCESS exception and the top 
of the stack is

0   libgnc-qof.1.dylib      0x00000001069cc83d qof_book_get_collection 
+ 61 (qofbook.cpp:510)

_wrap_gncOwnerGetOwnerFromLot + 126 (swig-engine.c:32929)

I don't have time to look into this right now since real life is 
intruding.  If no one else finds it, I'll either fix it or file a bug 
report later.
