[gentoo-user] Question about a strange emerge warning

Hi all.

Thanks to your support, I think I got a little bit of knowledge of how
emerge works, so I started cleaning my USE flags (I had lot of useless
stuff...).
To perform such cleaning, I started with USE=-* and than added everything I
needed.

It hasn't been very hard (but quite long :-) )to make things working: emerge
is a really cool tool.
However, I got this strange message:

 * Detected file collision(s):
 *
 *      /usr/lib/mozilla-firefox/defaults/autoconfig/prefcalls.js
 *      /usr/lib/mozilla-firefox/defaults/autoconfig/platform.js
 *
 * Searching all installed packages for file collisions...
 *
 * Press Ctrl-C to Stop
 *
 * net-libs/xulrunner-1.9.0.14
 *      /usr/lib/mozilla-firefox/defaults/autoconfig/platform.js
 *      /usr/lib/mozilla-firefox/defaults/autoconfig/prefcalls.js
 *
 * Package 'www-client/mozilla-firefox-3.0.14' NOT merged due to file
 * collisions. If necessary, refer to your elog messages for the whole
 * content of the above message.

If I understood, it seems that xulrunner and firefox package contains the
same files (prefcalls.js and platform.js) in the same directory.
Is it normal? Should I worry? Or I simply have to ignore it?

What makes me worried is: Package 'www-client/mozilla-firefox-3.0.14'
**NOT** merged

One more question : what is the difference between
www-client/mozilla-firefox and www-client/mozilla-firefox-bin ?

Thanks in advance,
Massimiliano

that is correct.

it is not normal and considered a bug. Should you worry -  see that is hard to 
answer - in most cases I have met, it is save to remove the already installed 
files, because the following app is providing exactly the same stuff.

But sometimes that breaks. In your case - I would move the two files into a 
backup dir in /root or somewhere else far away and save and retry. If 
everything works as expected (firefox is working, nothing is especially crashy) 
you can remove them.

-bin is already compiled. It is a binary package just like mozilla is 
distributing them. Advantage: instant joy. Disadvantage: sometimes slower, 
sometimes depending on stuff you really don't want to install.

Glück Auf

Do you have the 'xulrunner' USE flag set?  I believe you need to build
firefox with the xulrunner flag if you also want the xulrunner package
installed at the same time.  Not certain, but it's worth a try.

Thank you Volker, thank you Walt!

It seems that adding the xulrunner flag was the right way to go.

However

euse -i xulrunner

says

'Build native browser integration against xulrunner instead of firefox or
seamonkey'

So.. do I really need xulrunner? I think seamonkey is enought for me...

To answer I tried

equery d xulrunner

[ Searching for packages depending on xulrunner... ]
media-video/vlc-0.9.10 (nsplugin & !seamonkey? <net-libs/xulrunner-1.9.1)
                       (nsplugin&!seamonkey? >=net-libs/xulrunner-1.8)
www-client/mozilla-firefox-3.0.14 (xulrunner? =net-libs/xulrunner-1.9.0*)

but I'm not sure I've interpreted right the result...
Do it means that vlc-0.9.10 depends on an xulrunner version between 1.8 and
1.9.1 if I don't have seamonkey installed?

If that would be the case, I should simply emerge seamonkey, right?

(Sorry for the newbie questions: I'm doing my best to become as much
independent as possible!!)

Thanks a lot,
Massimiliano

Many packages can use xulrunner.  For example I have at least four packages
on my machine that use it:  firefox, thunderbird, totem, and yelp, so it
saves room and time for me to use xulrunner.  It's amazing how fast firefox
compiles if you already have xulrunner.

So, if you plan to use only seamonkey, and none of the other packages that
can use xulrunner, then it won't make any difference to you.  Bit if you
decide later to install one of those other packages then it will save time
and disk space to use xulrunner.

To see all packages that can use xulrunner, do 'quse xulrunner'.
