error installing indico 1.1.1 on RHEL6 "No module named persistent"

[bartelt]

This is my first time installing indico (or anything) with easy_install. I am a python newby. I am working on a newly installed RHEL6.4 (64-bit) server.
I did:
easy_install pip
pip install reportlab PIL

Those went fine. Then I did
easy_install indico
which did a lot of things, but then:

Please advise on how to proceed with the installation.
thanks, John

Hi,

Indico 1.1.2 has just been released. It should fix this issue. You should, however clean up your Zope python packages first, so, generally the ones starting with z* or Z* in your site-packages dir (e.g. /usr/lib/python2.7/site-packages/), as well as persistent.

[bartelt]

Thanks. What exactly do you mean by "clean up"? Can I just delete the .egg files?

[bartelt]

I googled and learned to use 'pip' to uninstall packages.

However, when I tried 'easy_install indico', I again got version 1.1.1.
When will the repository be updated to 1.1.2?

[bartelt]

Never mind, I forgot to uninstall indico itself.

Indico 1.1.2 fails also:

OK, weird. "easy_install -n indico" failed but "easy_install indico" succeeded.
