Yeah, that command line assumed a mach group already exists. I've tried
it with a separate /usr/sbin/groupadd -r mach before it, and without the
-g, and I have the same problem. 

Just now, I did userdel mach, groupdel mach, catted /etc/passwd and
/etc/group to make sure the entries were gone, and did a reinstall.

Heres the output from the rpm install (IMMEDIATELY after checking the
/etc/passwd and verifying that no mach user exists):

[root at mises root]# rpm -Uvh
/home/erik/rpm/RPMS/i386/mach-0.4.6.1-0.fdr.0.20040818.123455.i386.rpm

There is some sort of a lag in the pam library or something where it
handles /etc/passwd lookups.
