Looks like you have older version of python in your system.

How did you downgrad python to 2.7.10 ?

I used yum tar from the IBM site and installed with standard yum script ..yum.sh. I downgraded python using below command.

#rpm -Uvh python-2.7.10-1.aix6.1.ppc.rpm --replacefiles

There is no 2.7.11 python on AIX toolbox. So probably it was from some other source and overwriting that would have caused some conflict.

Some of the packages from different sources on AIX does not work on AIX because they are built with different decencies.

Is it possible for you to try on a machine that does not have any open source packages from any other repository and only from AIX toolbox.

Also one thing you can try updating to latest python from AIX toolbox and install required dependencies.

I have already done yum installation on many servers but iam stuck with this one. I tried removing all python filesets yum and reinstalled but it seems other packages which are already installed are on higher version than the yum tarball. I have below error now after reinstallation.

Skipping db-4.8.24-3 as higher version is installed already.
Please make sure these packages are from toolbox as there is no gurantee that
third party packages may be compatible with toolbox packages.

Skipping gdbm-1.8.3-5 as higher version is installed already.
Please make sure these packages are from toolbox as there is no gurantee that
third party packages may be compatible with toolbox packages.

Skipping gettext-0.10.40-8 as higher version is installed already.
Please make sure these packages are from toolbox as there is no gurantee that
third party packages may be compatible with toolbox packages.

Skipping glib2-2.14.6-2 as higher version is installed already.
Please make sure these packages are from toolbox as there is no gurantee that
third party packages may be compatible with toolbox packages.

server@root /root #> yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   Could not load module /usr/lib/libglib-2.0.a(libglib-2.0.so.0).
        Dependent module /usr/lib/libiconv.a(libiconv.so.2) could not be loaded.
        Member libiconv.so.2 is not found in archive
Could not load module /opt/freeware/lib/python2.7/site-packages/_sqlitecache.so.
        Dependent module /usr/lib/libglib-2.0.a(libglib-2.0.so.0) 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

This is the problem because of packages from other source.

Right now to me it looks like you have glib2 packages from some other repository and that is dependent on libiconv provided by same repository.

AIX toolbox provided glib2 is dependencies on libiconv provided by AIX. 

In this particular case when glib2 is getting loaded it is trying to find that libiconv and looks like it is not finding it.

The best solution is to remove all the rpms and start fresh.

One thing you can try otherwise to see if libiconv is installed as rpm or not ?

If not then please install it from the same repository from where you have installed glib2 and see if things works after that.

Thanks
