Must be. Just an update to what I said earlier. I compiled p7zip from
source and it did not work (actually the p7zip shell script does not
work on Solaris 9 since mktemp does not exist there, so I'm talking
about the binary 7z). And, I checked sfw and I found that a package
of p7zip was made available on Monday. So, I installed that. But,
I get the same error message so it's not just my fat fingers. That's
too bad since I just talked to PKWARE and if you have to ask, you can't
afford SecureZip.
