> - virtualenv + zc.buildout fails.  1.5.0b1 expected the -S of executables to work properly, and it doesn't for virtualenv.  This may not be fixable within virtualenv, per Carl's email.  I have a change to zc.buildout that I think will work around this in a local branch.  Tests fail, so it needs more work.  This is the most critical problem identified.

> - zc.recipe.testing's tests showed some API calls to zc.buildout that failed mysteriously.  I have not investigated that yet.  I know of several other existing recipes that use zc.buildout's API that work fine.  I'm hopeful that this will be easy to diagnose and address.
> - Tarek raised the problem that we can't easily handle beta packages of critical packaging infrastructure.  Jim countered with information on how buildout already does handle it.  However, I don't think that this helps with bootstrapping.  Moreover, it requires explicit configuration to get some of the behavior Jim describes.  I plan to address Tarek's concerns for now by having betas available through alternate means than PyPI.  However, this will require more active participation from you all to help prepare a smooth release on PyPI.

Thanks for your work !

for "beta" releases, you could use the "dev" tag, and leave the code
in the svn trunk. If the metadata of zc.buildout or properly set, we
can install the trunk like this:

$ easy_install zc.buildout == dev

in order to make this work, we need to add somewhere in the
documentation (long_description) a link to the svn trunk, followed by
an egg fragment marker, and release the metadata with it:


This will be scanned by easy_install and recognized as the dev
version. Pip is not compatible with this feature IIRC.
The bootstrap script should also work with this. People can force the
dev version in their buildout config as well, if the latest metadata
at PyPI has this dev marker.

This will make it easier for you to ask people to try the trunk before
you release it,
