_RLD_ROOT environment variable to point to the perl build directory.
-The only reliable answer is that you should specify a different
-directory for the architecture-dependent library for your -DDEBUGGING
-version of perl. You can do this by changing all the *archlib*
-variables in config.sh to point to your new architecture-dependent library.
