PSU Jul 2013 installed on RAC (Patch 16619892 on Linux 5)

I installed the patch on a two node RAC yesterday. Everything went Ok except I got normal warnings from precompilers (which we don't use) and I believe from some Cloud Control related things:
 2) OUI-67215:
 OPatch found the word "warning" in the stderr of the make command.
 Please look at this stderr. You can re-run this make command.
 Stderr output:
                             ins_emagent.mk:113: warning: overriding commands for target `nmosudo'
                             ins_emagent.mk:52: warning: ignoring old commands for target `nmosudo'
