Hi all,
I am deploying my Django app in sage-5.2-Ubuntu-10.04 on a Debian Wheezy.
Almost all succeeds but I need python psycopg2 in sage environment and I cannot make it working. My problem is verified when I import psycopg2:
#
ImportError: /usr/lib/x86_64-linux-gnu/libldap_r-2.4.so.2: symbol gnutls_certificate_get_x509_cas, version GNUTLS_1_4 not defined in file libgnutls.so.26 with link time reference
#
The symbol gnutls_certificate_get_x509_ca seems to be in /usr/lib/x86_64-linux-gnu/libgnutls.so.26 but not in /opt/sage-5.2-linux-64bit-ubuntu_10.04.3_lts-x86_64-Linux/local/lib/libgnutls.so.26 that is checked because of the LD_LIBRARY_PATH setting.
Follow the story on how to reproduce it
sage -sh
esay_install --upgrade psycopg2
First error:
Processing psycopg2-2.4.5.tar.gz
Running psycopg2-2.4.5/setup.py -q bdist_egg --dist-dir /tmp/easy_install-Vhfq2Z/psycopg2-2.4.5/egg-dist-tmp-sajtkC

Following http://stackoverflow.com/questions/6329887/compiling-problems-cannot-find-crt1-o and I have done:
ln -s /usr/lib/x86_64-linux-gnu /usr/lib64
esay_install --upgrade psycopg2
Installed. WOW! BUT...

I cannot find out the way to get out of this problem, please help me if you can.
Thank you very much Luca
