Oh, I see why it hasn't previously been an issue - the behavior varies according to whether both DT_RPATH and DT_RUNPATH, or just DT_RPATH, are defined in the program header; and when I build using default cc (clang), I get both tags (which makes LD_LIBRARY_PATH_RPATH unnecessary), whereas when I build using ports gcc using the recommended additional -Wl,-R option, for whatever reason that ends up setting only DT_RPATH. Confusing. Probably safest to add the env var anyway. -- Andrew (irc:RhodiumToad)
