Fix #629

 The LD_LIB_P_VAR *should* be *once* de-referenced in the echo statements within
 `prerequisits/install-functions/report_results.sh` so that it takes the value of
 `LD_LIBRARY_PATH` or `DYLD_LIBRARY_PATH` in the setup script, which then checks
 if the user has anything set here and decides whether to add additional search
 paths (if they have it set) or set it directly if it is empty.
