Thanks, Bill.

So here's what's odd:

diderot:/home2/jeff# grep-available -i ximian
diderot:/home2/jeff# apt-cache search ximian
diderot:/home2/jeff# apt-get -f install

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

Sorry, but the following packages have unmet dependencies:
  mozilla: Depends: libnspr4 (= M18-3) but 2:0.9.1-ximian.4 is to be installed
E: Sorry, broken packages
diderot:/home2/jeff# 

The install of mozilla would be cool but isn't critical for me. But
I'm bothered by the broken package that doesn't seem to be there.


I'm not quite sure how to reconcile the above with the following:

diderot:/home2/jeff# dpkg -l | grep ximian|wc -l
     64
diderot:/home2/jeff# 

All those packages are either ii (install/installed) or rc
(remove/config files).

Fwiw,
diderot:/home2/jeff# dpkg -l|grep 0.9.1-ximian.4  
ii  libnspr-dev    0.9.1-ximian.4 Netscape Portable Runtime library - developm
ii  libnspr4       0.9.1-ximian.4 Netscape Portable Runtime Library
rc  mozilla-browse 0.9.1-ximian.4 Mozilla Web Browser - core and browser
rc  mozilla-chatzi 0.9.1-ximian.4 Mozilla Web Browser - irc client
rc  mozilla-mailne 0.9.1-ximian.4 Mozilla Web Browser -  mail and news support
rc  mozilla-xmlter 0.9.1-ximian.4 Mozilla Web Browse - XML enabled
diderot:/home2/jeff# 

This is getting even odder. So I do

diderot:/home2/jeff# apt-get remove libnspr4
Reading Package Lists... Done
Building Dependency Tree... Done

I guess I kind of got what I want, but I'd love some help in
understanding what happened. I thought dpkg -l should be a subset of
apt-cache seach, for example.

    I met a man who wasn't there.
    He wasn't there again today
    I wish, I wish he'd go away.
