Hi there, I've been waiting for years for a release of buildout that contains proper isolation from Python's site-packages. The non-isolation is a major flaw in buildout that makes it SO much harder to write proper installation instructions for software such as Grok. We need to wrap Grok's buildout installation using virtualenv --no-site-packages. I just discovered that this installation actually fails if I use an ubuntu-installed virtualenv (or setuptools)! It works with a manually installed version of either, and I'm sure the problem is somewhere in z3c.autoinclude too, but it's still an issue. Last year in september I hacked up some code that would do the isolation. I was then informed that Gary was working on a branch instead, and indeed the branch I saw then looked much improved in features. So I waited. I saw new versions of the branch come and go and I'm not sure what's going on, but I waited. I noticed that in april there was a beta release of buildout that featured such improvements. This release was then withdrawn and overridden with 1.50b2 with the message: "This is a re-release of 1.4.3 to hide the brown-bag release of 1.5.0b1. The changes in 1.5.0b1 will reappear as 1.5.0 soon, when the additional reported problems have been addressed." It is now july, so I'm starting to get my doubts about the word "soon". Have the reported problems been addressed? Is there any hope I can get a buildout that actually provides proper isolation sometime? Can I help? Regards, Martijn
