One word of warning though, from someone who has been on this list for
a long time. I'm sticking my neck out with this one, but I dare to say
that *most* cases of trouble with i-Installer originate from having
Fink as well -- Gerben probably has more reliable statistics here. Be
very careful. The package above is great, but there are _still_
packages in Fink that blindly install Fink's idea of TeX.
At a more fundamental level: Fink adds its path _in front_ of the
standard path. This overrides all system defaults, and is against any
security practice on Unix that I know of. It means that a package
installed from the internet could conceivably install an application or
script that is called "ssh", hijacks your password (and then starts the
real thing, so you won't even notice it) and send the password off to
someone else. Since the path of Fink comes before anything else in the
system, there is nothing you can do about that, except type which ssh
each time you use it. Gerben did the correct thing by adding his
directories at the end of the path.
You can of course "correct" Fink by changing the /sw/bin/init.sh file
(make sure that $path or $PATH are _before_ any items that start with
/sw). I'd rather use a system that has considered security from the
