I am having problems emerging certain packages getting a "USE changes necessary" warning. VLC in this case - http://pastebin.com/0iMHQxaP . I emerged sys-libs/zlib-1.2.8-r1 and tried again and it still won't install. I also had this problem with Firefox but in that case I was able to install the Firefox-bin package, with Libreoffice the -bin wont install.... though I didn't spend a ton of effort tracking down what went wrong with Firefox after the -bin worked and not at all yet for LO. I can also emerge some other packages (I emerged some alsa files and installed Transmission between Firefox and VLC) - I assume I'm missing something basic here?

esue -a : http://pastebin.com/w450QnCV
dmesg: http://pastebin.com/VTNy8f1C
emerge sys-libs/zlib-1.2.8-r1: http://pastebin.com/0SYhdwRh

I realize this section is more oriented toward setting up the environment, but I didn't see a better place for it.

Thanks for the help!

Hi Aeons
configuration about use flag are stored under /etc/portage, but portage's default behavior is to not modify any file under /etc without your intervention
Modifies are stored in some "parallel files", in order to make you able to compare configurations without overwriting your settings

etc-update can help you in this task

Awesome, I was wondering how to deal with that. Is there a way to highlight only the changes in the document? Resolving them solved the issue for VLC.

Thanks :0)

Aeons ... that depends somewhat on how you want to manage these changes (ie, the editor), and what you've configured etc-update do when its run ... see: /etc/etc-update.conf ... eg:

/etc/etc-update.conf:
diff_command="vim -d %file1 %file2"
using_editor=1

... and note, 'etc-update' is one method of merging config changes, there is another, 'dispatch-conf'.

man dispatch-conf wrote:
Advantages of dispatch-conf include easy rollback (changes to config files are stored either using patches or rcs) and the ability to automatically update config files that the user has never modified or that differ from the current version only in CVS cruft or white space.

... and similarly to etc-update it can be configured to use some form of 'diff', and so provide a view of the changes to be merged, eg:

/etc/dispatch-conf.conf:
merge="vimdiff -c'saveas %s' -c next -c'setlocal noma readonly' -c prev %s %s"

best ... khay
