That's the most common install problem with psycopg2 -- setup.py can't  
find (or execute) pg_config which it needs to decide how to talk to  
Postgres. I remember it giving a different (and more descriptive)  
error but I haven't used psycopg2 recently.

To the OP: if executing pg_config fails from the same command line in  
which you're running setup.py, then Wolodja is absolutely correct. You  
need to get pg_config on your path somewhere, or there might be an  
environment variable you can set to tell setup where to find it if you  
don't want it in your path.

Good luck
