running build out Poi error

Hi I am receiving the following error any time i run the build  out.

Error: There is a version conflict.
We already have: Plone 3.3.4
but Products.Poi 2.0a1 requires 'Plone>=4.0a1'.

Here is my buildout.cfg


[buildout]
parts =
    zope2
    productdistros
    instance
    zopepy

# Change the number here to change the version of Plone being used
extends =
    http://dist.plone.org/release/3.3.4/versions.cfg
versions = versions


# Add additional egg download sources here. dist.plone.org contains archives
# of Plone packages.
find-links =

# Add additional eggs here
eggs =

        Products.Poi<2

# Use this section to download additional old-style products.
# List any number of URLs for product tarballs under URLs (separate
# with whitespace, or break over several lines, with subsequent lines
# indented). If any archives contain several products inside a top-level
# directory, list the archive file name (i.e. the last part of the URL,
# normally with a .tar.gz suffix or similar) under 'nested-packages'.
# If any archives extract to a product directory with a version suffix, list
# the archive name under 'version-suffix-packages'.

products =

    ${productdistros:location}

recipe = zc.recipe.egg
eggs = ${instance:eggs}
interpreter = zopepy
extra-paths = ${zope2:location}/lib/python
scripts = zopepy
