My bad, and I can now get something to work with for instance: python bootstrap.py --version 1.7.0 \ --distribute --setup-source=./thirdparty/dist/distribute_setup.py \ --download-base=./thirdparty/dist/
and a [buildout] with: include-site-packages = false install-from-cache = true newest = false allow-picked-versions = false # we need this in buidlout 1 too zc.buildout-version = 1.7.0 distribute-version = 0.6.34 # Weirdly enough buildout demands the files to be cached in a dist subdir # See https://github.com/buildout/buildout/issues/40 download-cache = thirdparty find-links = file:///thirdparty/ file:///thirdparty/dist/ > Again, I think this works by setting install-from-cache to true. > The original semantics of offline mode didn't fit it's name.

If anything the option name is as you said incorrect, and the "do not install" use case somewhat arcane and undocumented.

That would be the preferred approach IMHO Do you want a patch? Though I am not sure how to proceed to deprecate the option.... -- Philippe Ombredanne +1 650 799 0949 | pombreda...@nexb.com DejaCode Enterprise at http://www.dejacode.com nexB Inc. at http://www.nexb.com _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
