[Python] django db2

[cheis]

Salve,

sto cercando di installare django col supporto db2 su ubuntu 9.04. 
Seguendo quanto scritto su
http://code.google.com/p/ibm-db/wiki/ibm_db_django_README 

precisamente se faccio:

        # easy_install ibm_db
        Searching for ibm-db
        Reading http://pypi.python.org/simple/ibm_db/
        Reading http://code.google.com/p/ibm-db/downloads/list
        Best match: ibm-db 0.7.2.5
        Downloading

http://pypi.python.org/packages/source/i/ibm_db/ibm_db-0.7.2.5.tar.gz#md5=c5be803d94c86e18b54af69f101633f3
        Processing ibm_db-0.7.2.5.tar.gz
        Running ibm_db-0.7.2.5/setup.py -q bdist_egg

--dist-dir /tmp/easy_install-UCpBId/ibm_db-0.7.2.5/egg-dist-tmp-Z8TdtQ
        IBM DataServer environment not set. 
        Please set IBM_DB_DIR to path to sqllib,
        and set IBM_DB_LIB to lib directory under sqllib
        e.g. export IBM_DB_DIR=/home/db2inst1/sqllib
             export IBM_DB_LIB=/home/db2inst1/sqllib/lib
        
        No eggs found
        in /tmp/easy_install-UCpBId/ibm_db-0.7.2.5/egg-dist-tmp-Z8TdtQ
        (setup script problem?)

Cosa altro devo installare?

Grazie, ciao. Marco.
