 Py2app  and macholib raise the error "ValueError: New Mach-O header is too
 large to relocate".  The patches for configure.ldflags in
 portconfigure.tcl described here

 https://bitbucket.org/ronaldoussoren/py2app/issue/93/mach-o-header-may-be-
 too-large-to-relocate
 http://www.danplanet.com/blog/2009/02/15/using-py2app-with-gtk/
 https://trac.macports.org/ticket/29838

 do not fix the error.  I suspect some ports override default
 configure.ldflags.  Also, I think OpenCV triggers the same error:

 py2app's full output is attached.

 Env:  python27, py27-py2app, py27-macholib on OSX 10.8.

 Any guidance would be helpful.  There seems to be lots of confusion about
 this in trac and stack overflow.

 Thanks.
