Ho commentato tutti i riferimenti alla skin quintagroup.theme.chameleon e aggiunto PIL. Il buildout funziona e il quintagroup.plonecomments e' visibile, installabile e testabile.

codice:
[buildout]
parts =
    productdistros
    instance
    zopepy

# Change the number here to change the version of Plone being used
extends =
    http://dist.plone.org/release/4.0.4/versions.cfg
versions = versions





# Add additional egg download sources here. dist.plone.org contains archives
# of Plone packages.
find-links =
    http://dist.plone.org/release/4.0.4
    http://dist.plone.org/thirdparty
    http://dist.plone.org/thirdparty/PIL-1.1.6.tar.gz

# Add additional eggs here
eggs =
#    quintagroup.theme.chameleon
    quintagroup.plonecomments


# Reference any eggs you are developing here, one per line
# e.g.: develop = src/my.package
develop =
#       src/quintagroup.theme.chameleon





# 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'.
[productdistros]
# For more information on this step and configuration options see:

recipe = plone.recipe.distros

ftp-address = 10011

#debug-mode = on
#verbose-security = on
# If you want Zope to know about any additional eggs, list them here.
# This should include any development eggs you listed in develop-eggs above,
# e.g. eggs = Plone my.package
eggs =
    Zope2
    Plone
    PIL
    ${buildout:eggs}
environment-vars =
    zope_i18n_compile_mo_files true

# If you want to register ZCML slugs for any packages, list them here.
# e.g. zcml = my.package my.other.package
zcml =
    quintagroup.plonecomments
    quintagroup.plonecomments-overrides
products =
    ${buildout:directory}/products
    ${productdistros:location}
    ${buildout:directory}/hotfixes

[zopepy]
# For more information on this step and configuration options see:
# http://pypi.python.org/pypi/zc.recipe.egg
recipe = zc.recipe.egg
eggs = ${instance:eggs}
interpreter = zopepy
scripts = zopepy

[versions]
PIL=1.1.6
Provalo e lancia buildout in questo modo per avere un output piu' verboso:
codice:
bin/buildout -vvv
