I downloaded the 2.3.0 solaris build. Gunzip goes well. It gives me a checksum error while untarring. Then, I managed to start (tar xvif ignores checksums) it but there isn't at least the HTTPCacheManager product. I've got exactly the same error with 2.3.1b1 solaris tgz.
This keeps coming up, so I've added it to the FAQ.txt in the doc/ directory for 2.3.1: 1. On certain Unix platforms (usually Solaris) I get a "checksum error" untarring the Zope distribution. Whats the deal? Zope is built and distributed using GNU tar. Some vendor-supplied tar implementations have problems with long path names as they appear in GNU tar created files. This is a problem that occurs in a number of software distributions created using GNU tar, not just Zope. We suggest that you install a GNU tar on your system to avoid this problem (not just with Zope, but with other software distributions as well).
