I'm using virtualenv and I need to install "psycopg2".

I have done the following:

pip install 

http://pypi.python.org/packages/source/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160

And I have the following messages:

Downloading/unpacking http://pypi.python.org/packages/source/p/psycopg2/psycopg2 -2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160

Downloading psycopg2-2.4.tar.gz (607Kb): 607Kb downloaded Running setup.py egg_info for package from http://pypi.python.org/packages/sou rce/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160

Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH or specify the full executable path with the option:

python setup.py build_ext --pg-config /path/to/pg_config build ... or

with the pg_config option in 'setup.cfg'.

Complete output from command python setup.py egg_info:

My question, I only need to do this to get the psycopg2 working?

python setup.py build_ext --pg-config /path/to/pg_config build
