I am hoping someone (guess who :-) ) will chime in with the magic incantation to have the system not try to start modemmanger. I don't know If you meant me, but I'm going to try to answer anyway ;) The thing is, under the GNOME Grand View of How Things Should Work™, ModemManagar is never unneeded, since you don't actually *know* if and when you'll want to use a modem (there are *several* pieces of hardware that can be considered modems nowadays). The idea, as with everything else, is that if you plug/pair *anything* that could work as a modem, then it should Just Work™. As is the normal position with GNOME (if I understand correctly, which I think I do), they are interested in making the life easier for the regular case, and since everyone has a (potential) modem in their pockets right now in the form of a cellphone with bluetooth connectivity, the regular case is to have the system prepared to work with them, even if most GNOME users will never use their cellphones as modems. If you say my desktop computer has no bluetooth and I will *never* use any kind of modem with it, that's perfectly reasonably; but the GNOME devs will probably say something along the lines of that being a particular case, not the general one (which is technically true, BTW). So no, there is no magic incantation to have NetworkManager (is not the system, is NM) not try to start ModemManager. We could patch the code for that, and actually before GNOME 3.10 or 3.8, Gentoo did that; but with every new version of NM is harder and harder, since the GNOME devs make the (technically correct) assumption that everyone now has a modem for their computers, and they code under that assumption; so Gentoo stopped patching NM. I (like Todd) have ModemManager enabled. From what I can see, it is a single threaded process that uses basically no memory nor processor (it's idle until you connect/plug a modem), and that opens no ports to the outside world, so it doesn't brings any (obvious) security issues If someone wrote the necessary code to make ModemManager optional to NM, I think (but I could be wrong) that the Gentoo GNOME devs would take it; but it will never be accepted upstream. At this point I think I agree with them. Sorry if this doesn't help. Regards. -- Dr. Canek Peláez Valdés Profesor de Asignatura, Facultad de Ciencias Universidad Nacional Autónoma de México

They're important packages and the transition is important. There's no point in getting everything else updated, only to find you can't boot the system because of these. Right now, I would only worry about anything else if it prevented me addressing this matter. The only thing I'm noticed from above is weechat and conky depends from ncurses but glibc is not and other packages that depends builds fine(zsh, bash, mc). The glibc error looks to be related to gcc. What versions of gcc are installed, what does `gcc-config -l` say? Stroller.
