Problem installing psycopg2 in virtualenv (Ubuntu 10.04, Python 2.5)

[Pascal Polleunus]

Hi,

I've problems to install psycopg2 in a virtualenv on Ubuntu 10.04.


My problem is also explained on stackoverflow:
http://stackoverflow.com/questions/3847536/installing-psycopg2-in-virtualenv-ubuntu-10-04-python-2-5


I tried different things explained there: 
http://www.saltycrane.com/blog/2009/07/using-psycopg2-virtualenv-ubuntu-jaunty/

The last thing I tried is this...
I created a virtualenv with -p python2.5 --no-site-packages
I installed libpq-dev: apt-get install libpq-dev

In the virtualenv, I did this: easy_install -i 
http://downloads.egenix.com/python/index/ucs4/ egenix-mx-base

Then when I tried pip install psycopg2==2.0.7, I got this error:

Installing collected packages: psycopg2

Does anyone have any idea how to solve that?

Thanks in advance,
