|no pax headers||
This distribution is archived with PAX extended headers, which may be useful under some environments, but may also make extraction fail under other environments (Archive::Tar ignores PAX information as well).
If you use Mac OS X >= 10.6, use gnu tar (/usr/bin/gnutar) to avoid PAX headers. It's also important to rename (shorten) long file names (>= 100 characters) in the distribution.
This distribution has .pm files with inconsistent versions.
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
