You are right!
I'm using the latest yum bundle with some latest additional requried rpms. As you say, mixing older and newer rpms does not work.
yum needs tcl/tk as dependency.
The required libintl.so.1 is not included in the gettext version (0.19.7-1) of the latest yum bundle. Therefore gettext has to be downgraded to version 0.10.40-8.
These are the additional required rpms for the latest yum bundle (v5 of 13-Mar-2019) to install yum on AIX 7.1:
gettext-0.10.40-8.aix5.2.ppc.rpm
libxml2-2.6.21-4.aix5.2.ppc.rpm
tcl-8.4.7-4.aix5.2.ppc.rpm
tk-8.4.7-4.aix5.2.ppc.rpm
zlib-1.2.11-1.aix6.1.ppc.rpm
After installing the yum bundle with the additional required rpms, a yum update works like a charm.
As Nigel Griffiths says on the IBM support page AIX and yum - Get those Open Source apps on AIX the easy way:
I am assuming the latest AIX release AIX 7.2 TL2 sp2
If you are installing on older AIX versions then you may have a harder time.
Thanks for the illuminiation.

Your python is at 2.7.10 version and the libxml2 package is at 2.9.9 level. If you are using the yum bundle, then all the rpms are at the lower level . One can install the yum and yum update brings you at the latest and clean state.
But in your case , it's mix up and the error is nothing but a consequence of the dangerous "--nodeps" option.
This has nothing to do with the removal /usr symbolic links from the recent rpms. "/usr/lib/libiconv.a" comes from AIX base fileset and "/opt/freeware/lib/libiconv.a" comes from libiconv rpm. Creating a symbolic link between these two doesn't make any sense.

Hello,
I removed all rpm on this server and I'm going to install yum. After a rpm --nodeps -Uvh *.rpm I get the following dependency problem with a yum update:
root:/home/root# yum check-update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
0509-022 Cannot load module /opt/freeware/lib/libxml2.a(libxml2.so.2).
0509-150 Dependent module /usr/lib/libiconv.a(libiconv.so.2) could not be loaded.
0509-152 Member libiconv.so.2 is not found in archive
0509-022 Cannot load module /opt/freeware/lib/python2.7/site-packages/_sqlitecache.so.
0509-150 Dependent module /opt/freeware/lib/libxml2.a(libxml2.so.2) could not be loaded.
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.10 (default, Jun 22 2016, 05:57:59) [C]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq
root:/home/root# rpm -q libxml2
libxml2-2.9.9-1.ppc
root:/home/root# rpm -q libiconv

I think libxml2 has to link libiconv from /opt/freeware and assume this problem is caused by Removal of symlink/files from /usr for AIX Toolbox packages because not all packages take care of the symlink/files removal from /usr at the moment.
When I create a symlink from /usr/lib/libiconv.a to /opt/freeware the update will work but subsequently I get troubles with gettext and glib2 with libiconv.
root:/opt/freeware/lib# yum checkgettext-0.19.8.1-5.ppc has missing requires of libiconv.a(shr4.o)gettext-0.19.8.1-5.ppc has missing requires of libiconv.a(shr4_64.o)glib2-2.56.1-2.ppc has missing requires of libiconv.a(shr4.o)Error: check all
I'm afraid that the AIX toolbox packages are not in a clean state at the moment. I hope I'm wrong.
