Maybe this is the source of my latest problems (see the other thread on this).
And thanks for the info on sudo. I think you are right about ruby 1.8
for OS X--I'll post here if I find it, and I will install the complete
1.8 version and see what happens.

I just tried "sudo passwd root"

and got

[jacques-computer:~] sylvanjacques% sudo passwd root
Password:
root: No such file or directory
        0.00 real         0.00 user         0.00 sys
---
where  passwd was my password. I then did it with the word "passwd"
and got

 [jacques-computer:~] sylvanjacques% sudo passwd root
Changing password for root.
New password:
Password must be at least 5 characters long.
New password:
Retype new password:

So I changed my password--my old one was only 4 characters long.
I don't know if this enable root login though. I will find out later.
BTW, I have OS 10.2.8.
