Centos 5 Python 2.7, Cannot install Python-LDAP

Question

I need to install * Python-LDAP to run under Ptython 2.7

I have a Centos 5.8 system (I cannot upgrade to 6.x). I currently have Python 2.4 installed and also Python 2.7. I am using Python 2.7 for development (along with Django). I have Python-LDAP installed and working under Python 2.4 (it was installed using yum). I need to install Python-LDAP for use with Python 2.7 (I will also install Django-ldap). I have been trying for days to do this. yum only runs under Python 2.4 so I cannot use that. I downloaded the Python-LDAP source (python-ldap-2.4.13.tar.gz (md5) from https://pypi.python.org/pypi/python-ldap/ but when I try to build it I get errors (see below).

Does anyone know if/how I can install Python-LDAP for Python 2.7 on Centos 5?

I then looked over at this thread: https://mail.python.org/pipermail/python-ldap/2011q2/002937.html

So I downloaded the latest OpenLDAP and got:

./configure
Configuring OpenLDAP 2.4.38-Release ...
...
configure: error: BerkeleyDB version incompatible with BDB/HDB backends

Seems like I'm just sinking lower into a black hole...

This worked in centos 5.10 and python 2.7.6 . I installed into a virtualenv .

I see mentions of evolution-openldap in your logs which were in mine when I had the same issue. Those directories are installed by openldap 2.3x .

You don't need to build openldap from source as there is a version in yum that is new enough to satisfy the version requirement by python-ldap .

openldap24-libs.i386                 2.4.23-5.el5                     
openldap24-libs.x86_64               2.4.23-5.el5                     
openldap24-libs-devel.i386           2.4.23-5.el5                     
openldap24-libs-devel.x86_64         2.4.23-5.el5             

To install you should first yum install openldap24-libs openldap24-libs-devel .

edit setup.cfg so its [_ldap] section so it contains:

library_dirs = /usr/lib/openldap24
include_dirs = /usr/include/openldap24

Run the build again. (I deleted my old build/ directory, you probably don't need to but give that a shot if the above is not working).
