Hmm, -Wl,-R /new is wrong.
Either use -Wl,-R,/new or -Wl,-R -Wl,/new or -Wl,-rpath,/new.
The linker certainly doesn't demand the rpath to exist.
If you want to link against say that links against
in /old, but in the end will be in /new, you can use -rpath-link
too, i.e. gcc ... -Wl,-rpath,/new,-rpath-link,/old -L/old -l1

/etc/*.conf works well.
