Recycling of package names can very well have a real and honest
background, e.g. if someone decides to give a package name to someone
else for whatever reason. Happens in DNS all the time.

BTW: To address your repeatability/security concerns, the tools you are
using would also have to store the hash check sum of the downloaded
packages together with the version. AFAIK, buildout only pins down
versions, not MD5/SHA1 sums.
