Hugin can be tricky, especially if you're using the FastGL mode in an older version; the FastGL mode didn't really work for me until recently.

In addition to Alan's answer, note here that the above output lists
media-video/ffmpeg and also virtual/ffmpeg.
Unless you only installed ffmpeg for the first time recently then I'd guess you
originally installed media-video/ffmpeg (and that's what you have in your world
file).
If you were to install ffmpeg today you would install virtual/ffmpeg instead,
which is provided by either media-video/ffmpeg or media-video/libav.
Best thing to do is to remove video/ffmpeg from world in favour of
virtual/ffmpeg so that Portage can work things out for itself.

No, it means that ffmpeg and libav provide the same functionalityand
thus cannot both be installed on the same machine at the same time,
you need to pick one (libav is actually a fork of ffmpeg). See here:

This happens for several use flags (mp3 aac)
Does this mean that ffmpeg no longer supports mp3 x264 theora etc?
And if I need to codecise an mp3 I cannot use ffmpeg?

I did know, that this was removed. If I experience problems I'll remove the option, but maybe I'll remove it all together. I have systemd installed as I wanted to try, but I do not like the way everything is managed. I like the idea of simple bash initscripts, which can be easily extended if needed. I can also write bash scripts, which configure my system the way I want (i.e. set battery charging thresholds or something similar). I do not care for a split second advantage, but I just do not see a lot of point in waiting for bitlbee to start before xdm so that I might need maybe a while after I boot into my computer.

Yes it is. The initscripts themselves have such a mechanism, using the before and after statements, for example making sure that network services are started after the network is brought up. You can add your own rules to the daemons' config files in /etc/conf.d or to /etc/rc.conf.

[gentoo-user] gem install linecache19 fails
Hello, I do need the ruby-gem linecache19-0.5.12. Usually, there are two ways to install a gem, right? Via emerge and via gem install. But here, only one way works. dev-ruby/linecache only builds the ruby18-version of this gem, so I'm stuck with gem install. But gem install fails with the following error: trace_nums.c:(.text+0x22): undefined reference to `ruby_current_thread' I am using ruby-1.9.3p194, but tried with different versions as well. Does anyone have a clue what I can do to solve the problem and get linecache19-0.5.12 installed? Thanks in advance, Christian.

[gentoo-user] Runlevels, ordering initscripts and running them in background
Hello everybody, I was wondering if the following is possible: - Add a lot of daemons to a newly created runlevel post-default - Switch to it after the xdm is started (or after some time) I want to do this, so that I do not have to wait while non-crucial services are being started (e.g. fcron, bitlbee, ntpd to name a few). Maybe it is possible to somehow prioritize the initscripts? Another related question is that I come from Arch and there I could just give the *order* of the daemons/initscripts to start and some of them could be started and 'in background'. Is it possible to do that with openrc? I saw the rc_parallel option in rc.conf, but I do not know, whether I need anything else. Thanks for help, Ignas A.
