'equery depends automake' shows 44 packages, all depending on 1.10* or higher. So, can I safely emerge -C the other 2 versions? Should I (does it even matter)? Probably won't matter. A few packages actually specify an exact version of the autotools, but most just want a certain minimum version. If you try to install such a package in the future it 'should' re-emerge the required version of autoconf automatically. It might matter more if you want to install custom software independent of the portage system.

A few packages actually specify an exact version of the autotools, but most just want a certain minimum version. Portage doesn't allow ebuilds to specify minimum versions or ranges for automake, only exact versions. Specifying a mininum only works when putting automake as a dep in DEPEND. However, Gentoo devs are required to use WANT_AUTOMAKE, not DEPEND and WANT_AUTOMAKE only allows specific versions, not minimum ones. And this means multiple automake versions on the system are perfectly normal.

Oops, I was actually thinking of how the autotools can specify minimum versions of required libraries. Libraries != autotools :(

If emerge --depclean -a wants to remove one of both of them, let it, otherwise leave well alone. Understood, thanks... Just to be sure... the -a in the 'emerge --depclean -a' above will 'ask' me if I want to continue and remove the packages it finds, correct? Meaning, it won't just blindly go ahead and start ripping stuff out... How does that differ from 'emerge -p --depclean'? emerge -p will only print what it would merge/unmerge and then quits without asking. You can run this as normal user, no need to be root. emerge -a will print what it would merge/unmerge and then ask if you want to proceed. You have to be root to use this command. If you are not root and use emerge -a, portage will turn it into an emerge -p and tell you that it did so because you are not root.
