Hello,
I updated the Linux freeware packages on one LPAR with AIX 7.2 (last update was over a year ago).
I noticed when trying to run smbclient, then it would not load because it tried to load libiconv.a from /usr/lib instead of /opt/freeware/lib.
This happens because LIBPATH was set (containing both, among other settings).
Regardless of how I set it, some tool will fail (in my case, either smbclient or ksh93).
Only if I completely unset it, all tools work. But that creates problem with the LPAR's workload which requires a LIBPATH setting.
The problem would probably not happen if the libiconv.a dependency would be hardcoded in the Samba packages like described here:
