"I am trying to have "-Xlinker -headerpad_max_install_names" added to all ports' ldflags by modifying /opt/local/share/macports/Tcl/port1.0/portconfigure.tcl"
"I managed to build the dependencies for inkscape (the reason why I am doing all this) with "-Wl,-headerpad_max_install_names" added to portconfigure.tcl without apparent problem."
So it seems like the main reason to add the maximum header padding is so that one can modify the libraries with install_name_tool to be able to relocate them to outside MacPorts for inclusion in an application bundle ?
If instead including the application in MacPorts, there is no need for such relocation... Of course, there might be other reasons to modify the ldflags. Just like there are some valid reasons to modify cflags.
