It's easy to prepend or append to PATH in a Portfile, but I'm having difficulty seeing how to modify, rather than overwrite, DYLD_LIBRARY_PATH.
Usually you just want to set it, but now that it might or might not be set in legacysupport 1.1, I was hoping to just modify rather than overwrite it. I tried a number of different things, but couldn't spot the magic incantation...am i missing something simple? Thanks, Ken
