(__ZdlPv) can't be a weak definition
/opt/local/bin/odlibtool: internal link edit command failed

I think this is a bug because this problem only happens when crossing
Darwin/objc and __ZdlPv is a libstdc++ internal

I'm not really sure which .i to include though

Thanks for the comments.

I have many dynamic libraries in c++ all compiled with -flat_namespace.  
They all have
 U __ZdlPv

The only point of interrest I can add is that I get this error trying to build
the GNUstep version of poppler but I don't get this problem when building the
GNUstep version of xpdf.  The point, as you may know, is that poppler is the
same code as xpdf but bundled as a shared library.  And PopplerKit uses the
same objective C bridge approach than its predecessor, PDFKit.
