[gentoo-user] emerge --prune: should it work?

[Michael Higgins]

I attempted to emerge 'twinkle', a soft phone, but whoever made the ebuild neglected to include a dependency on KDE libraries.

Of course, since I don't have KDE libs, emerge failed. But before failing, the ebuild had pulled in, built, and installed two *new* packages.

As these packages were new dependencies only needed by 'twinkle' (which failed to install), I'd expect running emerge --prune immediately afterward to remove these unnecessary packages.

But it didn't. Something should, however.

Rather than my asserting that --prune is broken, since it apparently does *something* (just not what I'd expect), can someone give me a helpful clue as to what WILL remove these unneeded libraries? '-)

Cheers,
