Thanks Florent, that solved my question.

Please ignore comment #2. That seems to be a problem from a change in database table columns. I _was_ able to login after that was fixed.

Finally going to Python 2.6.7 and/or 2.7.2, built from tarballs. Difficult to locate, download, and install Python SRPM on CentOS, and as far as I could figure out, the build flags compared to a stock configure have enable-shared and disable-rpath (or something similar).

Sincere thanks for Florent for diagnosing the issue so well. I would have probably spent hours or days trying different variations of dependency installs!

Intalling the rpm in (from http://nightly.openerp.com/6.1/releases/openerp-6.1-1.tar.gz dated 23/2/2012) produces that same error on RedHat 6.2, Python 2.6.6 (r266:84292, Sep 12 2011, 14:03:02).

I submitted bug [Bug 940084] [NEW] Install / RedHat 6.2 / pip fails with InstallationError.

When is at last OpenErp going to work on RedHat ?

any solution?

Python 2.6.7 fix this issue

install phyton x86_x64 version 2.6.6-52. This fix the error "python: Python/compile.c:3437: stackdepth_walk: Assertion `depth >= 0' failed."

to verify try execute
   python -c "[1 for x in () if 1 if 1 if 1 if 1]"

yum install python.x86_x64
