Quick USE flags question [solved]

[Barrakketh]

If I had a package that wasn't installed (for example, live) but is an optional dependency of another package (continuing this example, mplayer), would adding the live USE flag to make.conf cause portage to pull in live and build it before mplayer if I didn't want to install it seperately? If so, would using --newuse cause it to download/build the package that provides that dependency as well?

Thanks.

I don't think "live" is an actual package, but rather a feature that may or may not be compiled into mplayer.
Apart from that: yes, dependencies are automatically solved by portage and it doesn't matter where these dependencies come from: a set or unset USE flag or the ebuild or wherever these thingies come from.
By "solved" I mean: satisfy the conditions to make the desired package work - so if there are other packages to be installed, portage "pulls them in" before compiling the actual package.

In short: yes.

Thanks. It's mainly to get my friend sorted out since he's recently started using Gentoo and I wanted to make it a bit easier to get some optional things sorted for him without trying to remember what exactly the package name was for things I installed long ago.

And live is a package

And live is a package :)

See what happens when you sit on a Windows box when writing in the forums? (Might have looked it up in the online repository though..)

I shouldn't be so fast in making general statements - I seem to be proofed wrong more often than I like ;)
