Yo have errors in Oracle client installation. You can correct them manually. But the simpler solution is:
1) remove content of /oracle/client/11x_64/instantclient_11202 directory
2) reinstall oracle instant client 11
3) rename /oracle/client/10x_64 directory to any you want (save it for some time)
4) create symbolic link 10x_64 -> 11x_64
Check the connection with R3trans -d.
